Given: A tank capacity as follows-
Barrels per cubic feet: 62.52
Barrels per cubic inch: 5.21
Barrels per cubic quarter inch: 1.3
Required: If there are 170 barrels deposited in the tank, then determine capacity in cubic feet, cubic inch and cubic quarter inch.
Explanation: Since it is given that

Suppose x cubic feet is the conversion for 170 barrels. Then by proportion-

Solving for x,

Similarly, if y represents the conversion for 170 barrels in cubic inch.
Then,

Finally, if z represents capacity in cubic quarter inch for 170 barrels then,

Final Answer: Capacity in cubic feet=2.72
Capacity in cubic inch=32
Capacity in cubic quarter inch=1.3
