The diagonal measurement of an 18 x 18 square is: 25.46 units.
One 18 inch x 18 inch tile = 1.5 ft x 1.5 ft = 2.25 sq ft.400 sq ft x 1 tile/2.25 sq ft = 177.77 = 178 tiles
18" = 1.5 feet 18" x 18" = 1.5-ft x 1.5-ft = 2.25 square feet
Since a square has right angles, you can use the Pythagorean Theorem to calculate the diagonal. Specifically, the diagonal of a square is equal to the length of a side, multiplied by the square root of 2.
18 in x 18 in = 1.5 ft x 1.5 ft = 2.25 sq feet.

330 sq ft. That allows for 10% waste. If laid on a diagonal allow another 10%.
To calculate the diagonal, use the Pythagorean Theorem.6^2 + 6^2 = x^236 + 36 = x^272 = x^2sqrt72 = xx = 8.485.....
One 18 inch x 18 inch tile = 1.5 ft x 1.5 ft = 2.25 sq ft.400 sq ft x 1 tile/2.25 sq ft = 177.77 = 178 tiles
Area = (x + 3)*(x + 10) = 120x^2 + 13x - 90 = 0 (x + 18)*(x - 5) = 0 Therefore x = -18 or x = 5. x = -18 gives sides of negative length and so is not a possible solution. Therefore x = 5 => A = 8 and B = 15 Then Diagonal = sqrt(8^2 + 15^2) = sqrt(64 + 225) = sqrt(289) = 17 metres.
A 24" by 18" tile is 432 square inches or three square feet.
18" = 1.5 feet 18" x 18" = 1.5-ft x 1.5-ft = 2.25 square feet

There are 2.25 square feet in 1 18" x 18" tile. Counting for NO waste, you would been 71 tile. Since tile this large with surely have some waste you will want to buy around 78 tile.
I assume 18 x 18 is in inches. That's 1.5 x 1.5 feet, or 2.25 square feet, for each tile. Just divide the total area by the area of each tile.
