Difference Between Cube and Cuboid

The main difference between cube and cuboid lies in their side lengths. A cube has six identical square faces with equal sides, whereas a cuboid has six rectangular faces where the length, width, and height can be different. Have you ever looked at a dice and a shoebox and wondered why they looked so similar, yet so different? They are both solid, box-shaped objects that take up space, but they are different shapes in geometry. You might ask, "Is a cube just a special kind of cuboid?" or "How do I calculate the space inside each?" This article explains the difference between cube and cuboid in a way that is easy to remember. By looking at cube vs cuboid features, you will learn to identify these shapes in your house and solve math problems with total confidence.

What is a Cube?

A cube is a three-dimensional solid shape bounded by six square faces. The most important thing to remember about a cube is that every single one of its sides is exactly the same length. Because all faces are squares, the length, width, and height are identical.

Example: A standard playing dice or a Rubik's cube.

What is a Cuboid?

A cuboid is also a three-dimensional solid, but its faces are rectangles. In a cuboid, the opposite faces are equal, but the overall length, width, and height are usually different. While a cube is perfectly symmetrical, a cuboid is often stretched out.

Example: A brick, a cereal box, or a pencil case.

Properties of a Cube and Cuboid

While they share some traits, the physical dimensions are what set them apart. Use this table to see the cube vs cuboid comparison clearly.

Feature	Cube	Cuboid
Shape of Faces	All 6 faces are Squares.	All 6 faces are Rectangles.
Side Lengths	All sides are equal (Length = Width = Height).	Sides can be different (Length, Width, and Height vary).
Symmetry	Highly symmetrical in all directions.	Less symmetrical; stretched appearance.
Diagonal Lengths	All 4 space diagonals are equal.	All 4 space diagonals are equal.
Relationship	A cube is a special type of cuboid.	A cuboid is not necessarily a cube.

Difference Between Cube and Cuboid with Examples

To truly understand what is the difference between cube and cuboid, let’s look at how we measure them in real life.

The Dice vs The Matchbox

If you measure a dice, you might find it is 2 cm long, 2 cm wide, and 2 cm high. Because all numbers are the same, it is a cube. However, a matchbox might be 5 cm long, 3 cm wide, and 1 cm high. Since the numbers are different, it is a cuboid.

Volume and Formulas of Cube and Cuboid

The math we use also changes based on their sides:

Volume of a Cube: Side x Side x Side.
Volume of a Cuboid: Length x Width x Height.

How to Identify Cube or Cuboid?

When you are looking at a 3D object, ask yourself these three questions:

Are all the faces flat? (Both have flat faces).
Are all the edges the same length? (If yes, it is a cube).
Are the faces shaped like rectangles or squares? (Squares mean cube; rectangles mean cuboid).

Remember, every cube is technically a cuboid because a square is a special type of rectangle. But not every cuboid can be a cube!

Difference Between Cube And Cuboid FAQs

What is the difference between cube and cuboid in terms of edges?

The main difference between cube and cuboid edges is that in a cube, all 12 edges are exactly the same length. In a cuboid, only the edges that are parallel to each other must be equal.

What is the difference between a cube and a cuboid using examples related to the kitchen?

An example of a cube related to the kitchen is a sugar cube or a piece of ice cut in the shape of a square using an ice tray. An example of a cuboid related to the kitchen could be a juice carton or a microwave oven.

Is it possible for a cuboid to have square faces?

Yes, it is possible for a cuboid to have square faces; however, if all six faces become squares, then it is not a cuboid; it is a cube.

Is a cube or cuboid more common in daily life?

The cuboid is much more common. Most items we use, like mobile phones, books, and buildings, are cuboids because they are rarely perfectly equal in all three dimensions.
