A cuboid is a 3D shape with six faces, twelve edges, and eight vertices. Each of its faces is a rectangle.
A cuboid is also a prism, as it has the same cross-section all the way through. It’s known as a rectangular prism.
Properties of a cuboid
- All cuboids have a height, length, and width.
- They have six faces, eight vertices, and 12 edges.
- The sides of the cuboids are rectangular.
- All the angles that are formed at the vertices are right angles.
What’s the difference between a cube and a cuboid?
There are a few similarities and differences between a cube and a cuboid – let’s look.
Similarities:
- Angles: a fun fact about cuboids is that they only contain right angles. If there are any other angles, then it’s not a cuboid. It is the same with cubes.
- Several edges, faces, and vertices: A cube and a cuboid have 12 edges, eight vertices, and six faces.
Difference:
- Faces: the main difference between a cuboid and a cube is the shape of their faces. A cube has six square-shaped faces, like a die. At the same time, a cuboid has six faces that are all rectangles. At least four of these rectangles are going to be identical too.
What are some real-life examples of cuboids?
We’ve made a list to help you with real-life examples of cuboids.
- Buildings: If you’re walking around a town or city, look at the buildings; many will be cuboids. Those exceptionally tall skyscrapers are built this way to make them strong. A cuboid shape also has enough space to fit offices and flats.
- Boxes: You’ll find that lots of boxes are cuboid shape. Look at the box, whether you’re walking around the supermarket, getting new shoes, or unwrapping a present.
- Microwave: Every microwave you’ll see is a cuboid. It is an efficient shape for what a microwave does. It can fit all the needed parts and be effective when warming your dinner!
- Books: Books are excellent examples of cuboids. The next time you’re in the library, see if you can find any books that aren’t cuboids. I bet it’ll be a struggle.
- Mobile phones: Mobile phones have changed over the years, but the newest ones are cuboids. It is because it makes it easy to hold. Imagine if your phone was a pyramid shape, it’ll be uncomfortable in your pocket, and you’d have trouble keeping it.
