Question

The volume of a rectangular solid is 3600 cm³. If it is 20 cm long and 9 cm high, find the width.

Answer 1

Given: Volume V = 3600 cm³, length l = 20 cm, height h = 9 cm; find width w.

Step-wise calculation:

1. Use V = l × w × h.

2. Solve for w: 

`w = V/(l × h)`

3. Substitute values: 

`w = 3600/(20 xx 9)` 

= `3600/180` 

= 20

The width is 20 cm.
