The measure of this occupied space is called the Volume of the object.

The area of the plane region occupied by each rectangle × height

= Measure of the space occupied by the cuboid

So, we get A × h = V

That is, **Volume of a Cuboid = base area × height = length × breadth ×** **height**

or l × b × h, where l, b and h are respectively the length, breadth and height of the cuboid.

**Note :** When we measure the magnitude of the region of a space, that is, the space occupied by a solid, we do so by counting the number of cubes of edge of unit length that can fit into it exactly. Therefore, the unit of measurement of volume is cubic unit.

Again

**Volume of a Cube = edge × edge × edge = `a^3`**

where a is the edge of the cube in following fig.

So, if a cube has edge of 12 cm ,

Then volume of the cube = 12 × 12 × 12 `cm^3`

=1728 `cm^3`.
