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

It will take 72 sq. ft. of sand. Or 2.66 sq. yds. That will fill the box even.
To calculate the amount of sand needed, first convert the depth from inches to feet: 2 inches is about 0.167 feet. Then, multiply the area by the depth: 452 square feet × 0.167 feet = approximately 75.5 cubic feet of sand needed.

You need 4.27 cubic feet. Weight in pounds is deceptive for sand depending on how wet or dry the sand is.

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.
Sand needed: 8*6*1.5 = 72 cubic feet
For 576 square feet at a depth of 4 inches, you will need 7.11 cubic yards.
