Assuming you pour to a depth of 4", you will need 1/3 cubic yards. If you go to 6" depth, you will need about 1/2 cubic yard.
At 4" deep, a 13' x 19' area needs at least 3.05 cubic yards of cement.
For this area you will need 2.4 cubic yards.
1.1852 cubic yards for every inch the pad is deep.
None. Just build the baseball field where the dirt is already there.
The width 12 feet is four yards, so the area would be 4 yards * 50 yards = 200 square yards. You would need 200 square yards of carpeting to cover that area.
If you the area of the gymnasium floor is 264 yards and the width is 11 yards, you can find the answer by dividing the area by the width. It would give you an answer of 24 yards.
4.23776 cubic yards
The radius would be 49.987 yards.
A square that has an area of four square yards would be two square yards on a side. Thus, the perimeter of such a square would be a total of eight yards.
Spread it evenly, then leave your hands in the cement for 4-6 hours to spread excess cement.
Multiply width by length to get the area. The answer would be 216 square yards.
15 yd by 15 yd square (educated guess???)
