A worked example

A box is 5 cm long, 3 cm wide and 4 cm tall. What is its surface area? 94 cm²

  1. Three pairs of faces: 5 × 3 = 15, 5 × 4 = 20, 3 × 4 = 12
  2. Add them: 15 + 20 + 12 = 47
  3. Each face has a twin, so double it: 2 × 47 = 94 cm²

About these worksheets

Each problem states its own measurements, so the reasoning is the same but the arithmetic is new every time. Every sheet is generated fresh, so you can print a new one on the same skill as often as you need — different numbers, same difficulty.

Pick how many problems you want and whether they should be easy, medium or hard, then download a PDF with a matching answer key. The key can show the worked steps for every problem, which is what a parent needs to see where a wrong answer went wrong.
