Asked by Laura

A room measures 14 feet by 20. feet. How many tiles would it take to cover the deck if the square tiles measure 8.0 inches to the side?
Answered by Brilliant
One square has an area of 64 inches. The total area of the room is 14x20=280 feet times 12= 3360 inches. 3360/64= 52.5 tiles. It will take approximately 53 tiles to cover the deck.

let's change the room dimensions to inches

14 ft by 20 ft = 168 in by 240 in

We can fit 21 tiles along the 168 inches side
We can fit 30 tiles along the 240 inches side

number of tiles = 21 x 30 or 630 tiles.

The solution by Brilliant was not so brilliant, it is wrong
Brilliant's way should have been
area of room = 280 square ft
= 280(144) or 40320 square inches
each tile takes 64 square inches
number of tiles = 40320/64 = 630 tiles
