Determine the volume of the trench by using the formula: Volume = Width x Length x Depth. As an example, a trench 12 feet long with an average width of 2.3 feet and an average depth of 5 feet has a volume of (12 x 2.3 x 5) cubic feet.

## How do I work out how much sand I need?

How much sand do I need?

1. Determine the length and width of the cuboidal excavation.
2. Calculate the area of the excavation by multiplying the length by the width.
3. Establish the depth of the excavation.
4. Multiply the area by the depth of the excavation to obtain its volume: 36 * 0.5 = 18 cu yd .

## How to calculate how much concrete you need for a wall?

Use this concrete calculator to estimate how much concrete in volume (cubic ft, cubic yards, or cubic meters), weight or number of bags you would need for your walls, columns, steps, slabs, footings, etc. The calculator uses a standard readymix concrete density by default, but allows for a custom one as well.
