Question

Area of the base of a cuboid is 30 cm². If its height is 6 cm, what is its volume ?​

Answer 1

★ Given:

Base area of a cuboid = 30 cm².

Height = 6 cm

★ To Find:

The volume of the cuboid.

★ Analysis:

We know that the volume of any 3D figure is the product of the base area and the height. The same property can be applied here.

★ Solution:

Base area = 30 cm²

Height = 6 cm

Volume = Base Area x Height

= 30 x 6

= 180 cm³

Therefore the volume of the cuboid is 180 cm³.

Important Formulae Related to Cuboid:

→ LSA = 2 (lh + bh)

→ TSA = 2 (lh + bh + lb)

→ Volume = lbh

Important Facts:

→ To find the area of a room to be whitewashed, then the formula to be used is 2 (lh + bh) + lb

→  To find TSA of a 3D figure, multiply the base perimeter with the height.

→ To find the volume of a 3D figure, multiply the base area with the height.
