Class 9 | Chapter 13 | Surface areas and Volumes | Exercise 13.5 | Question 8

Question 8: A solid cube of side 12 cm is cut into eight cubes of equal volume. What will be the side of the new cube? Also, find the ratio between their surface areas.

Cube & Cuboid

Finding volume of a cube or a cuboid is quite simple. Every cube/cuboid has 6 sides. All we need is multiply the length, breadth and height to find the volume or capacity. However, there is some difference between volume and capacity of an object. This has been explained in the video embedded in the end of the post. 

A cube is a cuboid that has all edges of equal length. Hence, every cube is a cuboid as well but every cuboid is not a cube. 

Volume of cuboid = length * breadth * height = l * b * h

Volume of cube = a³ ( where a is any edge of the cube)

It is recommended to understand the core concept of area, surface area and volume before we attempt any question based on these concepts.
