Gravel Calculator

To calculate how much gravel you need to cover a rectangular area you need to multiply the volume by the gravel density. The volume formula for a rectangular (or square) box in cubic feet is height (ft) x width (ft) x length (ft), as seen in the figure below: For example, to fill a box with a width of 3ft and a length of 6ft, to a depth of 1ft ...

 · 5$ per a retaining wall block, 2$ per a pound of gravel. In our example, the calculations go as follows: wall height / block height = 30ft / 10in = 360in / 10in = 36. wall length / block length = 10ft / 15in = 120in / 15in = 8. number of retaining wall blocks = 36 * 8 = 288. total cost of blocks = 5$ * 288 = 1,440$.
