How to Work Out the Volume of a Cuboid

Chapter 1

What a Cuboid Is (and How It’s Different from a Cube)

1

Faces, edges, and vertices of a cuboid

2

Length, width, height: naming the three dimensions

Chapter 2

Understanding Volume as “How Much Space Inside”

3

Volume vs area vs perimeter (don’t mix them up)

4

Visualizing volume with unit cubes (1 cm × 1 cm × 1 cm)

Chapter 3

Units for Volume (cm³, m³) and Unit Conversions

5

Reading and writing cubic units (cm³, m³, in³)

6

Basic metric conversions (mm ↔ cm ↔ m) before cubing

7

Converting cubic units (cm³ ↔ m³) and using powers of 10

Chapter 4

The Volume Formula for a Cuboid (Length × Width × Height)

8

Why the formula is L × W × H (stacking layers idea)

9

Step-by-step calculation examples

10

Checking your answer: reasonable size + correct units

Chapter 5

Measuring Dimensions Correctly

11

Measuring with a ruler/tape: choosing a consistent unit

12

Avoiding measurement errors (rounding, reading scales)

13

When dimensions are given in mixed units (e.g., m and cm)

Chapter 6

Practice, Word Problems, and Common Mistakes

14

Real-world word problems (boxes, rooms, tanks)

15

Working backwards: finding a missing dimension from volume

16

Common mistakes (forgetting to cube units, using area formulas)
