Volume of Composite Prisms & Pyramids — Easy Worksheet 2

Grade 7 · MathSheets    Name: ____________________   Date: __________

Find each volume (or missing measure). Figures are not drawn to scale.

How to solve

Split a composite solid into rectangular prisms, find each volume with V = l × w × h, and add them. A pyramid holds one third of a prism with the same base and height: V = 13 × B × h, where B is the area of the base. For a square base of side 6 and height 5, V = 13 × 36 × 5 = 60.

Example

The solid is made of two rectangular prisms. Find its volume in cubic units.
