You learn how to find the space inside plane shapes and the amount of space solids can hold. This helps you solve word problems on shapes, circles, and simple 3D objects.
You should already be comfortable with basic multiplication, division, and squares of numbers. It also helps if you can identify common shapes and read measurements accurately.

One question from this skill's own question bank, shown with its full working.
Find the area of a triangle with base 10 cm and height 6 cm.
Working: Area = ½ × base × height = ½ × 10 × 6 = 30 cm².
This topic normally appears in Junior High School work on geometry and measurement, where you practise applying formulas to shapes and solids. It also supports BECE-style questions that test accurate calculation and correct units.
Curriculum notes are a general guide to where this work normally sits. Always check the syllabus your school or examination body is currently using.
