Explanation

To find the total number of tiles required, we need to convert the floor dimensions from feet to inches and then divide the total area by the area of a single tile.

Floor dimensions:

5 feet = 5 x 12 = 60 inches (length)

4 feet = 4 x 12 = 48 inches (width)

Total area = length x width = 60 x 48 = 2880 square inches

Tile dimension:

10 square inches

Now, divide the total area by the tile area:

2880 ÷ 10 = 288

So, 288 tiles of dimension 10 square inches are required to cover the floor.
