Question

The length, breadth and height of a rectangle block are in the ratio 3 : 2 : 5 and its volume is 3750 cubic centimetres. 

Calculate the length, breadth and height.

Answer 1

Let breadth be 3x , length be 2x and height be 5x , then

3x × 2x × 5x = 3750

30 × 3 = 37

x = 5

Breadth = 3x = 3 × 5 = 15 cm

Length = 2x = 2 × 5 = 10 cm

Height = 5x = 5 × 5 = 25 cm
