## Unit 22 Section 6 : Volume of a Triangular Prism
This section looks at how to find the volume of a triangular prism.
A triangular prism has the same triangular cross-section throughout its length. ## Example QuestionThe diagram below shows a triangular prism:
(a) Calculate the volume of the prism if
Volume = area of cross-section × length The volume is 50 cm³
(b) Calculate the volume of the prism if We need all the units to be cm or cm², so we need to convert 2 metres into 200 centimetres.
Volume = area of cross-section × length
The volume is 2000 cm³
