Volume of CuboidsSEAG Practice Questions

Calculating the volume of cuboids using length × width × height, with answers in cubic units (cm³, m³).

Where your child meets this in real life: Working out how much water a fish tank holds or how many boxes fit in a shipping container

What your child needs to know

SEAGReady breaks volume of cuboids into 3 steps, taught in order so each skill builds on the last.

  1. 1

    Basic Volume Calculation

    Calculate volume of a cuboid using V = length x width x height with simple whole numbers

  2. 2

    Multi-Digit Dimensions

    Calculate volume when dimensions include two-digit numbers requiring multi-step multiplication

  3. 3

    Applied Volume Problems

    Extract dimensions from word problems and real-world contexts to calculate cuboid volume

Try the lesson: Basic Volume Calculation

This is the exact interactive worked example your child sees in SEAGReady. Step through it and watch the method build up.

Molly has a jewellery box that measures 4 cm long, 3 cm wide, and 2 cm high.

What is the volume of the box?

4 × 3 × 2

Identify the three dimensions
1

Length = 4 cm, Width = 3 cm, Height = 2 cm

Molly has a jewellery box that measures 4 cm long, 3 cm wide, and 2 cm high.

What is the volume of the box?

  1. 1

    Identify the three dimensions

    • Length = 4 cm, Width = 3 cm, Height = 2 cm
  2. 2

    Apply the volume formula

    • Volume = length × width × height
    • Multiply all three dimensions4 × 3 × 2 = 24
  3. 3

    Write the answer with units

    • Use cubic units for volumeV = 24 cm³

The volume of Molly's jewellery box is 24 cm³.

The key insight: Volume is like area, but with a third dimension - you're counting how many unit cubes fit inside!

Common mix-up: 4 × 3 = 12 cm². That's only the area of the base. Volume needs all THREE dimensions multiplied together.

Mistakes to watch for

These are the misconceptions we see most often in volume of cuboids, including the ones our practice questions are specifically designed to catch.

  • Confusing volume with area (forgetting the third dimension)
  • Using square units instead of cubic units
  • Multiplying only two dimensions
