Cuboid - The volume(capacity) of a cuboid is given by:
note: the sides of a cuboid are at right angles to eachother
Prism - a shape with variable length and constant cross-sectional area
Pyramid - The equation is independent of the number of sides of the pyramid. So the equation works equally for a tetrahedron(with a triangular base) and for other solids with differently shaped base areas.
Cone - This is similar to the pyramid, the area of the circle being the base area.
Frustrum This is the part of a cone remaining when a top section of the cone, parallel to the base, is removed.
volume of frustrum = [original vol. of cone] - [vol. of removed top section]
