Formula and worked example
Square pyramid: V = (1/3) a² h
Triangular prism: V = ½ b h × l
Example: a square pyramid with a = 4 cm, h = 6 cm holds 32 cm³ = 0.032 litres.

Questions people ask
What is the volume of a pyramid?
V = (1/3) × base area × height. For a square base of edge a, V = a²h/3.
How does a prism differ?
A prism keeps the same cross-section along its length, so V = base area × length, with no one-third factor.
