Area pf eacj tile=9 sq. inch =9/144 sq.ft
Therefore no. of tiles reqd.=4/(9/144)
=4*144/9=64

The table is square, so each side is 2 feet long. 2 Feet is equal to 24 inches so 8 tiles can go on each side. You have an 8 x 8 matrix of tiles which is equal to 64 tiles.
4 square feet = 2 feet x 2 feet
2 feet = 24 inches
24 inches / 3 in per tile = 8 tiles
8 tiles x 8 tiles = 64 tiles.

1 square foot=144 square inches based on 1^2=1 and 12^2=144
therefore 4 square feet would be 144 x 4=576 sq. inches
If each tile is 3 inches on one side then the total area would be 9 inches and therefore 576/4=64 tiles

The area is 4 sq ft, so it has to be a 2X2.
This is 24" X 24"
The total surface area is 576 inches.
But the tile measures 3 inches on One Side, so it has an area of 9 inches.
So it will take 64 of these tiles to cover the table area.

Each sq. ft is 12 inches by 12 inches.
Divide that by 3 inches, the size of the tile, and that's 4.
4 times 4 is 16 - so it will take 16 tiles to cover one square foot.
There are four square feet to cover: 4 x 16 = 64.
The answer is 64 tiles.
