The volume of the tank will be:

∏r

^{2}X12 ft^{3}= 603.20 ft^{3}Work is the act of changing the energy of a particle, body or system, in our case is force times space so the total weight is

40X603.20 = 24128 lb

The space will be 6 ft

and the work is

24128 X 6 = 144768 ft-lbf =

196276 Joules.
