A ballast tank is 19 ft long, 25 ft wide and 7 ft deep. Find its maximum capacity in tons if it is filled with seawater?( 1 ton of seawater=36 cu ft)

Solution:

The volume of tank = 19*25*7 = 3325 cu ft

Because 1 ton of seawater=36 cu ft

So 3325 cu ft/36 cu ft = 92.36 tons

So its maximum capacityis 92.36 tons
