Assuming the last "8" is also in feet, just multiply 16 x 16 x 8. The answer will be in cubic feet. If the 8 is in inches, divide by 12 first, to convert to feet.
To calculate the volume of sand needed to fill the sandbox, multiply its dimensions: 50 ft (length) × 1 ft (depth) × 1 ft (width) = 50 cubic feet. Therefore, you will need 50 cubic feet of sand to fill the sandbox.

To determine the amount of sand needed to fill a 6' x 6' sandbox, you also need to know the depth of the sandbox. Assuming a standard depth of 1 foot, the volume would be 6' x 6' x 1' = 36 cubic feet. Since a cubic yard contains 27 cubic feet, you'd need approximately 1.33 cubic yards of sand to fill the sandbox.
15 * 5 * 0.5 = 37.5 cu ft. or 1.39 cu yards.

It will take 72 sq. ft. of sand. Or 2.66 sq. yds. That will fill the box even.
15 * 5 * 0.5 = 37.5 cu ft. or 1.39 cu yards.
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.
