A microwave, a tissue box, and a shoebox, what do you think they have in common? Yes! They are cuboids. Let’s learn five crazy facts about cuboids for kids. A cuboid is a solid, three-dimensional shape with six faces. But here is where it gets “crazy”—every single one of those faces is a rectangle! Because they have flat sides and straight edges, cuboids are the ultimate team players in construction.
You can stack them high, line them up side-by-side, or pack them into a truck without wasting any space. From the tiny bricks used to build your house to the giant shipping containers that travel across the ocean, cuboids are the “building blocks” of our modern world.
A three dimensional shape is a solid shape that has three dimensions: length, width, and height. Three dimensional rectangular shaped objects are known as ‘cuboids’. A rectangle is the two dimensional version of a cuboid. It is one of the most commonly seen shapes around us. Cuboid means “like a cube”.
A cuboid has 6 sides or faces, twelve edges and eight vertices. Unlike a cube, all the edges of a cuboid are not the same length. A cuboid had 4 rectangular faces and two square faces. The four rectangular sides of a cuboid are identical. A cuboid has 4 lateral faces and 2 faces of top and bottom. Lateral faces are The lateral face of a three-dimensional shape is the face that is on its side instead of on its top or its bottom.
Everyday you see many cuboid shapes without even realising it. Many boxes such as shoeboxes, food containers are in the shape of cuboids. Microwaves are also in the shape of a cuboid and nearly all books you own or see are cuboid in shape! Look around your home and see what is a cuboid shape, maybe it’s a chest of drawers or a jewellery box?
A cuboid is also a prism. It’s known as a rectangular prism. A prism is a type of three-dimensional shape with flat sides. A prism object has two ends that are the same shape and size and it has the same cross-section all the way through. This means that if you cut through it you would see the same 2D shape as on either side.
Did you know that a cuboid shape only contains right angles? This is one of the main ways you can tell if a shape is a cuboid or not, if all angles are not right angles then the shape is not a cuboid. The opposite edges of all cuboids are also parallel to each other. These features make cuboids easy to distinguish. This is also similar to cubes shapes.
