If you’re not sure which type of sand to get, we like Quikrete play sand which you can order online or probably find at Lowes, Home Depot, or another local hardware store. So, if you need 15 cubic feet of sand as an example, you will need to buy 30 bags of sand. Like I said earlier, each sand bag should be 0.5 cubic feet. Once you’ve figured out the depth, use this formula to get the volume in cubic feet:ĭon’t forget to convert your depth from inches to feet! So, for example, 6 inches equals 0.5 feet. When using products that you plan to compact down like gravel fines for pathways or yellow sand for a base under paving, an.
We recommend 4-6 inches of sand in your sandbox. You’ll then square the radius and multiply by Pi to get the area.Īrea = π*r^2 How Deep Do You Want the Sand? Take the diameter of the sandbox and divide it by two to get the radius.
#SAND VOLUME CALCULATOR HOW TO#
Heading back to high school geometry class, the shape of your sandbox will determine how to calculate that volume.įor rectangular sandboxes, use this formula to get the area first:įor round sandboxes, it’s a bit more complicated. To determine the number of sand bags you need, we have to figure out the volume of sand to fill your sandbox, measured in cubic feet (most standard sand bags are 0.5 cubic feet). The followings are the typical value of different types of sand.Step-by-Step Calculation: How Much Sand You Need In Your Sandbox What Shape of Sandbox Do You Have? Now by adding the masses to get the total mass of the substance, which is proportional to the total weight.
Third: We have to know the mass densities (or specific gravity) of the constituent materials.Second: We have to know the volumetric percentage of each constituent material in one unit of the substance.For other types of sand, may have mixtures of quartz, gypsum, or silica. In the Sand, assumed it was a mixture of the minerals olivine and basalt. First: We have to know the constituent materials of the substance. The calculator computes the weight (1) and volume (2) of gravel using the following formulas: (1) m × V and (2) V l × w × h, where is the density, V volume, m weight (or mass), and h is the height of gravel l and w and are the length and width of a base of an aquarium respectively.Sand weight calculator also has to be taken. To calculate the unit weight of sand, we have to know some information, the volume of one unit of sand, the composition of the sand, and the mass densities of each component. Measuring the unit weight of soil in the field may consist of a sand cone test, rubber balloon, or nuclear densometer. Unit Weight, is usually determined in the laboratory by measuring the weight and volume of a relatively undisturbed soil sample obtained from a brass ring. In another word, the Unit weight of sand is the ratio of the total weight of sand to the total volume of sand. The following table represents the typical dry density values for different types of sand. Unit weight or Specific Weight of sand is calculated by the product of the density of sand and the standard gravity of sand.Īccording to the US customary measurement system, dry weighs 1.631 gram per cubic centimeter, this density is equal to 101.8 pounds per cubic foot. In this article, details about unit weight of sand, how to determine it, and typical unit weight values of different sand types will be presented. The standard gravity is usually given in m/s 2 of ft/s 2, and on Earth usually taken as 9.81 m/s 2. The density of the material is the per unit volume, calculated in the unit of kg/m 3 or lb/ft 3 (pcf). Don’t forget to convert your depth from inches to feet So, for example, 6 inches equals 0.5 feet. Once you’ve figured out the depth, use this formula to get the volume in cubic feet: Area x Depth Volume in cubic feet. And the specific weight of a material is actually the product of its density and the standard gravity. We recommend 4-6 inches of sand in your sandbox. The first thing is Unit weight is as same as Specific Weight.
