Gravel refers to small rounded stones mixed up with sand. These small rounded stones that are called gravel are used in earthwork projects. There are many types of gravel and all are listed down.
To calculate the volume needed, use the gravel cost calculator or follow the given steps:
A surface has \(18 ft\) long and \(21 ft\) wide with a depth of \(10 ft\). Then how much gravel do I need?
Solution:
\(L = 18 ft\)
\(W = 21 ft\)
\(D = 10 ft\)
So, find the area by,
\(A = L \times W\)
\(A = 18 \times 21\)
\(A = 378 ft^2\)
Now,
Calculate the volume by using the formula:
\(V = A \times D\)
\(V = 378 \times 10\)
\(V = 3780 ft^3\)
To calculate the weight needed, using the formula:
\(Density = \frac {mass}{volume}
\(mass = Density \times volume\)
If the volume needed is \(3780 ft^3\) and the density is \(104.88 lb/ft^3\), then find the weight needed?
Solution:
Here,
\(Density = 104.88 lb/ft^3\)
\(Volume = 3780 ft^3\)
So,
\(mass = Density \times volume\)
\(mass = 104.88 \times 3780\)
\(mass = 396446.4 lbs (198.223 tons)\)
Calculating rock needs:
Material | Suggested Depth | Coverage Area per 1 ton |
3”-8” rock | 3”-8” | 60 square feet |
1”-3” rock | 1”-3” | 80 square feet |
3/4”-1” screened gravel | 2” | 100 square feet |
5/8”-1/2” screened gravel | 2” | 120 square feet |
1/4-3/8” screened gravel | 2” | 140 square feet |
