# Egg-Shaped Tank - Feet - Three Measurements

This tank is in the shape of an egg, and requires three measurements to calculate volume, capacity and surface area. This calculator uses feet for measurements, requiring the diameter at the widest part of the egg shape, plus two height measurements from above and below this point.

##### 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

#### Calculator

- enter the length A in feet
- the length B in feet
- the diameter of the tank in feet
- the weight of the liquid in pounds per US gallon

#### Results

- the volume of the egg-shaped tank in cubic feet
- he volume in cubic inches
- the volume in cubic metres
- the tank capacity in US gallons
- the capacity in Imperial gallons
- the capacity in litres
- full tank liquid weight based on lbs/gal US
- the surface area of the tank in square inches
- the surface area in square feet
- the surface area in square millimetres
- the surface area in square metres

##### Formula

V = 2/3𝝅(D/2)²H
where V is the volume
𝝅 = 3.14159265
D the diameter of the egg tank on its widest point
H the height of the egg
