Sarah is laying tiles on her floor which is a rectangle with dimensions: 4' * 7'
Each tile is a square with dimensions 8" * 8"
The area of the floor is 4*12*12*7 = 4032 square inches.
The area of each tile is 8*8 = 64 square inches.
This gives the number of tiles required to cover the floor as 4032/64 = 63.
As each box has 15 tiles she would need 5 boxes so that she does not fall short of tiles, as 4 boxes only contain 60 tiles.
TheĀ required number of boxes of tiles is 5.

The floor measures 4 by 7 .
We need to find the number of (8x8) tiles to cover the floor.
I am assuming the the tiles measure 8" ( 8 inches)
We will convert the sides of the floor to inches.
We know that 1 foot = 12 in.
==> The width = 4 ft = 4*12 = 48 in.
==> Then we need 48/8 tiles = 6 tiles for the width.
==> The length = 7 ft = 7*12 in = 84 in.
==> Then we need 84/8 tiles = 10.5 tiles.
Then the total number of tiles to cover the area is 6*10.5 = 63 tiles.
Each box contains 15 tiles.
==> 4 boxes contains 4*15 = 60 tiles.
==> 5 boxes contains 5*15 = 75 tiles
Then we need 5 boxes to cover the floor.
