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
Each SEAG paper has 28 maths questions. Questions 29 to 50 are multiple choice with five possible answers, and questions 51 to 56 need a short written answer. With 56 questions in 60 minutes across English and maths, that is about a minute per question.
SEAGReady breaks volume of cuboids into 4 steps, taught in order so each skill builds on the last.
Find the volume of a cuboid built from 1 cm cubes by counting one layer and multiplying by the number of layers
Calculate volume of a cuboid using V = length x width x height with simple whole numbers
Calculate volume when dimensions include two-digit numbers requiring multi-step multiplication
Extract dimensions from word problems and real-world contexts to calculate cuboid volume
Try three free questions from our volume of cuboids course. They start easy and get harder, so you can see where your child's confidence runs out. If they manage the last one without a hint, this topic is probably secure. If not, the steps above show where to start.
This cuboid is built from 1 cm cubes. How many cubes are used?
The cube-shaped die shown has equal edge lengths. What is its volume?
George says the volume of the storage crate shown is 360 cm³. Is George correct? If not, what is the correct volume?
This is the exact interactive worked example your child sees in SEAGReady. Step through it and watch the method build up.
Conor builds a cuboid from 1 cm cubes. It is 4 cubes long, 3 cubes wide and 2 cubes high.
How many cubes does he use?
4 × 3 × 2 = ?
The top layer has 3 rows of 4 cubes
Step 1 of 4
Conor builds a cuboid from 1 cm cubes. It is 4 cubes long, 3 cubes wide and 2 cubes high.
How many cubes does he use?
Conor uses 24 cubes, so the volume is 24 cm³.
The key insight: Count one layer, then count the layers - some cubes are hidden, but every layer is the same.
Common mix-up: 26 cubes. That counts the squares on the outside faces you can see. Hidden cubes are inside and behind.
These are the misconceptions we see most often in volume of cuboids, including the ones our practice questions are specifically designed to catch.
Struggling with volume of cuboids? The real gap is often in one of these earlier topics.
