Question

Martin wants to put tile down on his kitchen floor. The floor is 9 feet long and 8 feet wide. Each tile is 6 inches by 6 inches. How many tiles does he need to cover the floor

Answer 1

"288 tiles" does he need to cover the floor.

Step-by-step explanation:

Given,

The length of the floor (l) = 9 feet = 9 × 12 inches = 108  inches and

The breadth of the floor (b) = 8 feet = 8 × 12 inches = 96 inches

To find, the total number of tiles = ?

∴ The area of the floor = The length of the floor (l) × The breadth of the floor (b)

=  108  inches ×  96 inches

Also,

The area of tiles = 6  inches × 6 inches

∴ The total number of tiles$= \dfrac{The area of the floor}{The area of tiles}$

$=\dfrac{108 inches\times 96 inches}{6 inches\times 6 inches}$

$=\dfrac{108\times 96}{6\times 6}$

= 3 × 96

= 288

∴ The total number of tiles = 288

Thus, "288 tiles" does he need to cover the floor.
