I can calculate the volume of prisms.
Volume - Volume is the amount of space occupied by a closed 3D shape.
Prism - A prism is a polyhedron with a base that is a polygon and a parallel opposite face that is identical. The corresponding edges of the two polygons are joined by parallelograms.
When questions are in context, the length may be described as the depth or height and this can cause some pupils to struggle if they have learned a formula with a particular word.
Remind pupils that the volume of a 3D shape comes from a product of three perpendicular lengths. The cross-sectional area uses two of the three, so identify the distance that is perpendicular to the cross-sectional face.



















Base: 2 cm by 3 cm - Height: 20 cm
Base: 5 cm by 2 cm - Height: 12 cm
Base: 15 cm by 2 cm - Height: 4 cm
Base: 8 cm by 3 cm - Height: 5 cm
Base: 10 cm by 4 cm - Height: 3 cm
