Assuming your measurement is in feet - 400 square feet of timer.
That's 2.4691 cubic yards. (rounded)

Well honey, a 20x20 area equals 400 square feet. A sheet of 4x8 plywood covers 32 square feet. So, you'll need 13 sheets of plywood to cover that 20x20 space. Math doesn't lie, darling.
The diagonal of a square room can be calculated using the Pythagorean theorem. For a 20x20 room, the formula is (d = \sqrt{20^2 + 20^2}). This simplifies to (d = \sqrt{400 + 400} = \sqrt{800} = 20\sqrt{2}), which is approximately 28.28 feet. Thus, the diagonal of a 20x20 room is about 28.28 feet.

That depends on what depth you want the concrete !
