A rectangular water reservoir contains `105\ m^3` of water. Find the depth of the water in the reservoir if its base measures 12m by 3.5m.

Explanation

Given,
Capacity of water reservoir `= 105 m^3`
Length of base of reservoir` = 12` m
Width of base `= 3.5 `m
Let depth of reservoir `= h `m
So,
` => l xx b xx h = 105`
` => 12 xx 3.5xxh = 105 `
`=> h =frac{ 105}{ 12 xx 3.5} = 2.5` m
Depth of reservoir =` 2.5` m
