The wall - concrete volume equation computes the volume of concrete needed in a wall based on its length(l), height(h) and width(w). concrete wall (prison) The volume (V) is computed in cubic units such as cubic yards. However, vCalc provides automatic conversions into many other volume units such as cubic meters and feet. These are the SYSTEM units.
For the DIY crowd that mixes their own concrete, vCalc will let the user convert the SYSTEM cubic units to the number of bags of concrete in the following sizes:
Once you have your answer in cubic units, click on the SYSTEM button and choose the size of bag (above), and vCalc will tell you how many bags you need for that volume of concrete.
The basic formula is as follows:
`volume = height * "length" * width`
