Volumes
Volume calculations for rectangular prism and pyramid are shown below:
A truncated pyramid is a pyramid which top has been cut off.
If the A1+A2 is almost equal in size then the following formula can be used instead:
V = h × (A1 + A2) / 2
A prismoid is as a solid whose end faces lie in parallel planes and consist of any two polygons, not necessarily of the same number of sides as shown opposite, the longitudinal faces may take the form of triangles, parallelograms, or trapeziums.
