The ansew is 286.75 because if you multipy 15.5 times 18.5 and you get 286.75 and if you add 12 plus 25 equals 37 and if you add 286.75 + 37=323.75

you will need 12 boxes of tiles becasue I founld the area of and then divided it by 25 because there are 25 tiles in a box and the when I got that and 11.47 and the you get 12 becasue other wise you will be short some tiles

16+19 is equal to 35. So you need 35 boxes.

18 boxes because you would times 15.5*18.5, then you would divide by 12 and divide again by 25 to get your answer of 18

1 because you only need 23 tiles. because first I found the area of the ractangular floors. then I devided it by 12 and I got 23 so I think only 1

I got the answer 11.47, and what i did was take 18.5 and 15.5 and times them. Then the number i got was the number i divided by 12. And thats how i got 11.47 .

12 boxes of tiles because you have to take 15.5 times 18.5 and then you get 286.75 and then you take 25 into 286.75 and you get 11.47 and then you want to get 12 boxes so you have anough of the tiles.

you will need 12 boxes because if you multiply 18.5 x 15.5 = 286.75 square feet.then mutiply 25x12=300 then 300 divided by 12= 25 so there is 25 feet per box and if you divide 286.75 by 25 = 11.75 so you will need about 12 boxes if you round.

three boxs of tiles you will need to have because if u add 15.5 +18.5=34/25=1.36 34/12=2.83 i did was i took the tottly by 25 to see how many i will need to get

Anonymous said...

you will need 2 boxes because 1 tile equals 1 ft. on each side so you got to add 15.5 and 18.5 together you get 34 so you will need 2 boxes and you will have extra

you will need one box because if oyu take 15.5 and 18.5 multiply the ndivied by 25 you get 11.47

First you take 12(inches on each side) times 25 (sold in one box)and you get 300. Then you take 15.5 x 18.5 and get 2867.5. So I think you will need 2867.5 tiles to complete this task.

I know that this is probally wrong but I think you would only need one box because if you times the length and width then i divided that by 12 and i got 23.89583333 so you only need one box.

Anonymous said...

15.5 plus 18.5 plus 12 times 2 = 58 and then you take 58 - 25 and you get 33 boxes.

One tile is 1' by 1' so the area is 1'. The area of the room is 286.75 feet in area. So then take 286.75 divided by 25 because thats how many tiles are in a box. The answer is 11.47. So you need 12 boxes, and you will have extra because you only need part of the box.

286.75 because 15.5 x 18.5= 286.75

you will need 13 boxes because you take 18.5 times 15.5.

The rectangle is 18.5 by 15.5, So you take 18.5 times 15.5 which equales 286.75 then you take 286.75 divided by 25 and that equales 11.47 and that rounds to 11.5, so you would need 12 boxes of tiles.

you will need 12 boxes because you need to find the area, so 15.5 times 18.5 is 286.75 and 25 times 12 equals 300 squares and 300 is more than 287 but 11 times 25 is only 275 which is not enough, so you need 12 boxes of 25 squares.

you will need about 7 packs because twele times 7 is 375

You need 12 boxes because you take 18.5 divided by 12 and then you take that answer divided by 18.5 and then you can determine that you nedd 12 tiles per foot on that side and you take 12 times 18.5 and you get 222 and divide that by 25 and you get 8 boxes . And you do the ame with 15.5 and you figure out that you need 8 tiles per foot and then you take 8 times 15.4 and you get 124 and take that divided by 25 and you get about four so in that means you'll need 12 boxes.

You would need 1 box and 9
I took each number by 12 and added them together and then I divided them by 12 to get 34.

you would need to buy 3 boxes because a square block is 12 in witch is 1 foot so if u box is 25 feet. than the four sides equal 3 boxes so you would need 3 boxes.

I have no idea!!!...dont get it!!!!

Well on this one I don't know what it is so I kinda guessed on it and i just figured that it was 15.5 + 18.5 = 34 so I didn't really get it so I guessed on it

Anonymous said...

The answer would be 6 boxes.
if you multiply 18.5 x 15.5= 286.75
it you devide 286.75 by 48 it would equal 6 when rounded

Anonymous said...

it is 12 boxes, first you do 15.5 X 18.5= 286.75 divded by 25=12 boxes

12 boxes of tiles will be needed. First, find out the roofs area by multiplying 15.5 and 18.5 = 286.75. Since the tiles are 12 on each side, take (12 x 12) divided by 286.75 and you get 11.9. So about 12 boxes of tiles will be needed.

you would need 5 1/2 boxes

to figure out how many boxes of tile to fill the rectangular room you will need to do:
15.5x18.5= 286.75 then you need to do 25 divided by 286.75 then you get 11.47

you need to get 11.47 boxes of tile

you would need 12 boxes.
I converted the sides of the rooms into inches by multiplying by 12 since that is what my tiles are in. Then I took the base 222 in times hieght 186 to get 41292. then, I divided it by 144 because that is the area of the tiles. i got 286.75, then I divided that by 25, because there are 25 tiles per box and got 11.47, which is the number of boxes needed. Since you can't use fraction of a box I rounded to 12

Anonymous said...

I think the answer is 3441in. because I took 15.5x18.5x12=3441 thats how I got that answer.

Anonymous said...

12 boxes, you have to do 15.5 times 18.5. Then divide it by 25.

Anonymous said...

the answer is 25. what I did is I took 15.5 times 18.5 and got 286.75 feet. then I took that and divided it by the area of the tiles which is 1 foot. Then I didvided that number by 25 and got 11.47, so I rounded that up to 12 because you can't get 11.47 boxes of tile.

i took 18.5 x 15.5 and i got 286.75ft. and then i took that divided by 25 and i got 11.47.i divided that because there are 25 tiles in a box.

12 boxs, because I took 18.5 x 15.5 and got 286.75,and then divided that by 25.

i did it wrong the first time so i will try to show you what i did before i got told the right answer. i took 15.5 x 18.5 = 286.75 divided by 12 = 23.9 and so i got the 1ST time that you would only need 1 box. BUT I NOW KNOW THAT ITS WRONG

Anonymous said...

7.25 becuse you take 15.5 times 18.5= 286.75 then you take 25+12=37 take 286.75/37=7.5

Anonymous said...

First you have to take the rooms size whitch is 15.5 and 18.5 and multiplie them together. you end up with 286.275 then you round your number up to 287 because when you purchase your item you cant get a fraction of a tile then you divid 287 by 25 to get your answer of the amount needed. so your answer is 12 boxes

Anonymous said...

the answer is 86025
i got thins answer by multiplicating all the # together to get the answer.

Anonymous said...

well you take 15.5x18.5=
and you take you answer/12
and you get about 23.89
so you would order one box andhave some left over

you need 25 tiles

Anonymous said...

12boxes 11 would be a few to less so to cover the whole flore you need 12.

First, I took 18.5 times 15.5 and got 286.75 to get the area. And then I took 12 times 25 = 300. The anser is 12 boxes of tiles if you round.

Anonymous said...

15.5ft X 18.5ft=286.75
286.75/25=11.47
Boxes=12 boxes

You take 15.5 times 18.5, because that is the area of the room. Then you divide 286.75 divide by 25, because there is 25 tiles per box. The answer is 12 boxes because you wouldn't have enough tiles if you got 11 boxes.
