Sandbox Calculations

First find the area of the sandbox in feet

3 feet long by 3 feet wide

Calculate the total area in Square Feet by multiplying Length x Width

Length x Width = Square Feet

3 x 3 = 9 square feet

Find the volume of the sandbox by finding the depth and convert to feet (inches divided by 12)

Depth ÷ 12

4 ÷ 12 = 0.33 cubic feet

Calculate the cubic feet of the sandbox my multiplying Area by depth

Area x Depth (in feet) = Cubic Feet

16 x 0.33 = 2.97 cubic feet

Find the cubic feet in a bag of playsand

Quikrete Playsand is 0.5 cubic feet

Calculate the number of bags needed by dividing the total cubic feet by the amount of cubic feet per bag of sand.

Cubic Feet ÷ Cubic Feet per bag = Number of bags

2.97 ÷ 0.5 = 5.94 bags of sand

For larger sandboxes (or sandpits) you may need to have your local supply yard deliver sand to your house. Our sandpit at headquarters is 10 feet x 10 feet x 1 foot deep.

To calculate the yards of sand needed, divide cubic feet of the sandpit by 27 (27 cubic feet in 1 yard)

Area ÷ Cubic Feet in a yard = Number of Yards

100 ÷ 27 = 3.7 yards

Our sandpit is 100 cubic feet and would need 200 bags of sand or 3.7 yards.
