Question

A cuboidal vessel is 10 m long and 8 m wide. How high must it be made to hold 380 cubic metres of a liquid ?

Answer 1

Volume of cuboidal vessel, V = 380 m³ . 

length, l = 10 m breadth, b = 8 m height, h = ? 

Volume of vessel, V= l × b × h 

380 = 10 × 8 × h 

380 = 80 h

∴  h = \(\frac{380}{80}\)

∴ h = 4.75 m.
