Question

A vessel in the shape of a cuboid is 30 cm long and 25 cm wide. What should be its height to hold 4.5 litres of water ?

Answer 1

Length of a cuboidal vessel (l) = 30 cm breadth (b) = 25 cm height (h) = ? 

The volume of water m a cuboidal vessel = 4.5 Lts.

= 4.5 × 1000 cm³ 

= 4500 cm³

∴ l × b ×h = 4500 

⇒ 30 × 25 × h = 4500 

⇒ h = 4500/(30 x 25)

∴ h = 6 cm 

∴ Height of the vessel (h) = 6 cm
