Truncated Funnel Tank
Calculate the volume, capacity, and surface area of a funnel tank.
The funnel tank here has the shape of an upside down truncated cone with the bottom section cut off perpendicular to the top.
Approximate weight of Fuel or Water
one US gallon of water = 8.34 pounds. one US gallon of diesel fuel = 7.1 pounds one US gallon of gas = 6 pounds
Note: measurement used in the calculation is the diameter length, not the radius length!

Formula
V = 1/3𝝅H(T²TBB²) where V is the volume of the tank 𝝅 = 3.14159265 T half the tanks' upper diameter B half the tanks' bottom diameter H the height of the tank
