12-104.

**truncated pyramid**. It is formed by slicing and removing the top of a pyramid so that the slice is parallel to the base of the pyramid. If the original height of the square-based pyramid at right was 12 cm, what is the volume of this truncated pyramid? (Hint: You may find your results from problem 12-84 useful.) Homework Help ✎

Find the volume of the top of the pyramid and subtract this from the volume of the whole pyramid.

*V* = 324 − 12 = 312cm³
