To calculate the amount of sand needed to fill a sandbox measuring 4 feet long, 4 feet wide, and 2.5 feet deep, first find the volume by multiplying the dimensions: 4 ft x 4 ft x 2.5 ft = 40 cubic feet. Therefore, you will need 40 cubic feet of sand to fill the sandbox. If you're purchasing sand, check the bag specifications to determine how many bags you'll need based on their volume.

It will take 72 sq. ft. of sand. Or 2.66 sq. yds. That will fill the box even.
Another 53.75 square feet of tile would be needed.

The answer will depend on the depth to which the area is covered.
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
