Q3 of 75 Page 228

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

Let the height of the cuboidal vessel be h

Length (l) of vessel = 10 m


Width (b) of vessel = 8 m


Volume of vessel = 380 m3


l × b × h = 380


[(10) (8) h] m2 = 380 m3


Therefore, the height of the vessel should be 4.75 m
