Enter the base lengths, height, and depth into the calculator to determine the volume of a trapezoidal prism.

## Volume Calculation Formula

The following formula is used to calculate the volume of a trapezoidal prism:

Volume = ((Base1 + Base2) / 2) * Height * Depth

Variables:

- Base1 (a) is the length of one of the parallel sides (units)
- Base2 (b) is the length of the other parallel side (units)
- Height (h) is the distance between the parallel sides (units)
- Depth (d) is the depth of the prism (units)
- Volume is the space occupied by the prism (units³)

To calculate the volume, first
