Question

The areas of three surfaces of a cuboid are 10 m2, 18 m2, and 20 m2. What is the volume(in m3) of the cuboid.

A.

48

B.

36

C.

56

D.

60

Correct option is D

Given:

Areas of three surfaces of a cuboid = 10 m2, 18 m2, and 20 m2​

Formula Used: 

Volume of cuboid = Length × Breadth × Height 

Solution: 

The area of the three faces of a cuboid can be represented as:

Area of the first face = Length × Breadth = 10 

Area of the second face = Breadth × Height  = 18 

Area of the third face = Length × Height  = 20 

Multiply the three equations: 

(Length × Breadth × Height)2  = 10 × 18 × 20 

(Length × Breadth × Height)= 3600 

Length × Breadth × Height = 3600\sqrt{3600}​ = 60

Thus, the volume of the cuboid is 60 m3
