Lesson summary

Measurement is a part of our daily lives, from buying a bag of rice to building a house. Today, we will focus on a specific type of measurement called volume. Volume helps us understand the amount of space an object occupies or how much a container can hold. Think about the "polytank" at home; its volume tells us how much water it can store. Or a box for shipping yams; its volume determines how many yams can fit inside. Understanding how to calculate the volume of common shapes, called prisms, is a crucial skill for construction, business, and even cooking.

Lesson notes

a) What is a Prism?

A prism is a three-dimensional (3D) solid object with two identical ends (called bases) that are parallel to each other. The sides are flat faces. The key feature of a prism is that it has the same cross-section all along its length.

Imagine a loaf of "butter bread". No matter where you slice it, the shape of the slice is the same rectangle. That loaf of bread is a rectangular prism (a cuboid). Base: The identical, parallel faces that give the prism its name (e.g., a triangular prism has two identical triangles as its bases). The base is not always at the bottom! Height (or Length): The perpendicular distance between the two bases. b) The General Formula for Volume of a Prism

This is the most important rule you need to remember. The volume of *any* prism can be found using one single formula:
