Practice Nets in Math

Use these practice problems to test your method after reviewing the concept explanation and worked examples.

Quick Recap

A net is a two-dimensional layout of faces that folds into a three-dimensional solid.

Unfold a 3D solid like a cardboard box—the flat connected pattern you get is a net of that solid.

Example 1

easy
Draw and describe the net of a rectangular prism (box) with dimensions 5 cm \times 3 cm \times 2 cm, and use the net to find the total surface area.

Example 2

medium
Describe the net of a regular triangular pyramid (tetrahedron with equilateral triangle faces) with edge length 6 cm. Find its total surface area using the net.

Example 3

easy
How many faces does a triangular prism have, and what shapes are they? If the triangular base has base 4 cm and height 3 cm, and the prism length is 10 cm, find the surface area using a net.

Example 4

hard
A cylindrical can has radius 3 cm and height 10 cm. Describe its net and find the total surface area.
