Q4 of 77 Page 21

A rectangular water reservoir contains 105 m3 of water. Find the depth of the water in the reservoir if its base measures 12 m by 3.5 m.

Given,


Capacity of water reservoir = 105 m3


Length of base of reservoir = 12 m


Width of base = 3.5 m


Let depth of reservoir = h m


So,


=


=


= 2.5 m


Depth of reservoir = 2.5 m
