1.	What is volume of cubes and cuboids? What are the formulas?
Answer» Cube and cuboid are three-dimensional shapes which consist of six faces, eight vertices and twelve edges. The primary DIFFERENCE between them is a cube has all its sides equal whereas the length, width and HEIGHT of a cuboid are different. Both shapes look almost the same but have different properties. The area and volume of cube, cuboid and also cylinder differ from each other. In EVERYDAY life, objects like a wooden box, a matchbox, a tea packet, a chalk box, a dice, a BOOK, etc are ENCOUNTERED. All these objects have a similar shape. In fact, all these objects are made of six rectangular planes. In mathematics, the shape of these objects is either a cuboid or cube. Here, in this article, we will learn the difference between the two shapes with the help of their properties and formulas of surface area and volume. Cube Cuboid Total Surface Area = 6(side)2 Total Surface area = 2 (Length x Breadth + breadth x height + Length x height) Lateral Surface Area = 4 (Side)2 Lateral Surface area = 2 height(length + breadth) Volume of cube = (Side)3 Volume of the cuboid = (length × breadth × height) Diagonal of a cube = √3l Diagonal of the cuboid =√( l2 + b2 +h2) Perimeter of cube = 12 x side Perimeter of cuboid = 4 (length + breadth + height)

Cube and cuboid are three-dimensional shapes which consist of six faces, eight vertices and twelve edges. The primary DIFFERENCE between them is a cube has all its sides equal whereas the length, width and HEIGHT of a cuboid are different. Both shapes look almost the same but have different properties. The area and volume of cube, cuboid and also cylinder differ from each other.

In EVERYDAY life, objects like a wooden box, a matchbox, a tea packet, a chalk box, a dice, a BOOK, etc are ENCOUNTERED. All these objects have a similar shape. In fact, all these objects are made of six rectangular planes. In mathematics, the shape of these objects is either a cuboid or cube. Here, in this article, we will learn the difference between the two shapes with the help of their properties and formulas of surface area and volume.

Cube Cuboid

Total Surface Area = 6(side)2 Total Surface area = 2 (Length x Breadth + breadth x height + Length x height)

Lateral Surface Area = 4 (Side)2 Lateral Surface area = 2 height(length + breadth)

Volume of cube = (Side)3 Volume of the cuboid = (length × breadth × height)

Diagonal of a cube = √3l Diagonal of the cuboid =√( l2 + b2 +h2)

Perimeter of cube = 12 x side Perimeter of cuboid = 4 (length + breadth + height)
