Example 12: A child playing with building blocks, which are of the shape of cubes, has built a structure as shown in Fig. 13.25. If the edge of each cube is 3 cm, find the volume of the structure built by the child.
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.
