32 cubic ft.

Volume of sand required = 7 ft * 7 ft * 1/6 ft = 49/6 cubic feet = 8.166... cubic ft.

All you have to do is find the maximum volume of your sandbox. To do this, multiply the length (6 ft.) by the width (6 ft.) by the depth (10 ft.). 6 x 6 x 10 = 360 cubic feet This is if you want to fill the sandbox to the brim. If you want something about half the depth so that the sand isn't falling out everywhere, you just multiply: 6 x 6 x 5 = 180 cubic feet

6 inches = 1/2 footVolume = 1/2 x 3 x 3 = 4.5 cubic feet = 1/6 of a cubic yard

Sand needed: 8*6*1.5 = 72 cubic feet

To calculate the amount of soil needed, you multiply the area by the desired depth. In this case, you have 9300 square feet and want a depth of 12 inches. Convert the depth to feet (12 inches = 1 foot) and multiply: 9300 square feet x 1 foot = 9300 cubic feet of soil. So, you need 9300 cubic feet of soil to cover the area with a depth of 12 inches.

For 576 square feet at a depth of 4 inches, you will need 7.11 cubic yards.

You convert everything to compatible units. Then you multiply area x depth. I suggest you convert the depth to feet; in that case, the answer will be in cubic feet.
