Question

The length and breadth of a rectangular solid are respectively 25 cm and 20 cm. If the volume is 7000 cm³, find its height.

Answer 1

Given: Length = 25 cm, Breadth = 20 cm, Volume = 7000 cm³.

Step-wise calculation:

1. Volume formula for a rectangular solid:

V = length × breadth × height

2. Solve for height:

height = `V/("length" × "breadth")`

3. Compute denominator:

25 × 20

= 500

4. Compute height:

7000 ÷ 500

= 14

Height = 14 cm.
