Question
Joanna wants to tile a square floor that measures 8 feet on one side. If each tile is a 6-inch square, how
many tiles will she need for the floor?
O 64 tiles
O 192 tiles
O 256 tiles
O 324 tiles

Answer 1

The number of tiles needed to cover the floor is 256 tiles.

The given parameter:

the length of a side of the floor = 8 feet

the length of a side of the tile, = 6-inches

To find:

• how many tiles she will need for the floor

Convert the unit of the floor to inches

1 ft = 12 inches

8 ft = (8 x 12) = 96 inches

The area of the floor = 96 in x 96 in

The area of the floor = 9216 in²

The area of a tile = 6 in x 6 in

The area of a tile = 36 in²

The number of tiles needed to cover the floor:

$number \ of \ tiles = \frac{Area \ of \ floor}{Area \ of \ a\ tile} = \frac{9216}{36} = 256 \ tiles$

Thus, the number of tiles needed to cover the floor is 256 tiles.
