Answer:
Step-by-step explanation:
So the tiles he will used to cover the floor are in inches but the measurement of his floor is in feet.
First let's convert the dimensions of the floor into inches. 12 inches = 1 foot
5 feet = 5 x 12 inches = 60 inches
8 feet = 8 x 12 inches = 96 inches
From these new measurements you can find the are of the floor in inches, length x width
60 x 96 =5760 inches squared
Now he wants to cover the floor in 3 inch square tiles, so to find how many he needs we dived the area of the floor by the area of one tile.
5760/3 = 1920 tiles
