Which chapter does this paper follow?

It follows the Primary 5 chapter on volume of cuboids and cubes, covering direct volume, reverse height or edge, capacity conversion and cutting.

Why insist on units in every answer?

Volume and surface area can share a number but never a unit; writing the unit is the cheapest self-check and carries marks in school tests.

Primary 5 Maths: Volume of Cuboids and Cubes — 10 Practice Questions with Answers

2026-10-29

Tutor Prep Guide · Primary Maths

Most lost marks in volume questions come from units, not multiplication: cm³, m³ and litres are mixed up, or surface area is given instead of volume. Every item here requires a unit.

Quick answer　10 questions, about 25 minutes. Items 03, 04 and 07 work backwards to a height or edge, and item 06 needs a litre conversion; mark after finishing everything.

FoundationA cuboid is 6 cm long, 4 cm wide and 3 cm high. Find its volume.
FoundationA cube has edges of 5 cm. Find its volume.
FoundationA cuboid has volume 120 cm³, length 8 cm and width 5 cm. Find its height.
FoundationA cube has volume 64 cm³. Find its edge length.
IntermediateA cuboid is 1.2 m long, 0.5 m wide and 0.4 m high. Find its volume.
IntermediateA tank is 50 cm long, 30 cm wide and 40 cm high. How many litres can it hold?
IntermediateA cuboid has volume 2.4 m³ and base area 1.5 m². Find its height.
ChallengeA cube has edges of 4 cm. Find its total surface area.
ChallengeA cuboid 10 cm by 6 cm by 4 cm is cut entirely into 2 cm cubes. What is the largest number of cubes?
Error redoA cuboid is 7 cm long, 3 cm wide and 2 cm high. Find its volume. (common slip: giving surface area instead)

03　Answers and one-line notes

#	Answer	One-line note
1	72 cm³	Length × width × height.
2	125 cm³	All three edges are equal: 5 × 5 × 5.
3	3 cm	Height = volume ÷ (length × width) = 120 ÷ 40.
4	4 cm	Find the number that gives 64 when cubed.
5	0.24 m³	Multiply step by step: 1.2 × 0.5 = 0.6, then × 0.4.
6	60 L	Volume is 60,000 cm³, then ÷ 1000 to get litres.
7	1.6 m	Height = volume ÷ base area, since base area already covers length × width.
8	96 cm²	Surface area covers six faces: 6 × 4 × 4, which is not the volume.
9	30 cubes	Each direction gives 5, 3 and 2 pieces; multiply to 30, after checking each divides exactly.
10	42 cm³	7 × 3 × 2 = 42 in cubic centimetres; surface area would be in square centimetres.

04　What to do after marking

After marking, redo only the wrong items and write down which step went wrong (formula, unit, or misread number).
Repeat the same item two days later; move to the next paper only when both attempts are correct.
Parents only need the answer and note columns; there is no need to explain every item.
