Work out wedge volume instantly with clear inputs, formula shown and shareable results.
A wedge has a rectangular base a × b tapering to a top edge of length c at height h. Prismatoid integration gives V = (bh/6)(2a + c).
Wedge volume
V = (b·h / 6)(2a + c)
The wedge becomes a triangular prism of volume abh/2, which the formula returns.
It becomes a pyramid-like wedge with volume abh/3.
