**drwls**, Sunday, April 12, 2009 at 5:59amFirst compute the total area.

Floor and ceiling are 30x40 = 1200 sq ft each.

Two walls are 40 x 12 = 480 sq ft (each)

The other two wall are 30 x 12 = 360 sq ft (each)

Add them up and subtract the window area of 40 sq ft.

A = 2(1200 + 480 + 360) - 40 = ?

For the number of tiles needed, divide by the area of each tile, which is (2/3)^2 = 4/9 sq ft per tile.

**Damon**, Sunday, April 12, 2009 at 10:08am8 inches = 8/12 = 2/3 feet

so

8*8 = 64 in^2

or

2/3 * 2/3 = 4/9 ft^2 as Dr WLS said

You calculate the ares in square feet and divide it by 4/9 ft^2 /tile

In other words multiply the square feet needed by 9/4
