Volume of a Cuboid Formula: How to Calculate & Examples

The volume of a cuboid formula is V = l × w × h, where l is the length, w is the width, and h is the height. Volume is the amount of space inside the cuboid, measured in cubic units (cm³, m³).

How to Calculate the Volume of a Cuboid + Example

Steps:

1. Find the length (l), width (w), and height (h).
2. Multiply all three: V = l × w × h.

Worked Example: An aquarium shaped like a cuboid has a length of 8 cm, a width of 5 cm, and a height of 4 cm. What is its volume?

Solution: V = l × w × h = 8 × 5 × 4 = 160 cm³

So the volume of the aquarium is 160 cm³.

Why It Matters for Students

The volume of a cuboid is a foundational Solid Geometry topic in Grade 5–6 and is developed further in junior high. It is useful in daily life — finding the capacity of boxes, cupboards, pools, or delivery trucks.

Fun fact: A cube is really a special cuboid whose length, width, and height are equal, so the formula V = l × w × h becomes V = s³.
