# Truncated Cone Tank Calculate the volume, capacity, and surface area of a truncated cone tank. A truncated cone tank is a cone where the top part is cut off parallel to its base.

##### 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! `

#### Calculator

1. the top diameter in inches
2. base diameter in inches
3. truncated cones' height in inches
4. the weight of the liquid in pounds per US gallon

#### Results

1. the volume of the truncated cone tank in cubic inches
2. the volume in cubic feet
3. the volume in cubic metres
4. the tank capacity in US gallons
5. the capacity in Imperial gallons
6. the capacity in litres
7. full tank liquid weight based on lbs/gal US
8. the surface area of the tank in square inches
9. the surface area in square feet
10. the surface area in square millimetres
11. the surface area in square metres

##### Formula
```V = 1/3𝝅((T/2)²+(T/2)(B/2)+(B/2)²)H;
where V is the volume of the truncated cone
𝝅 = 3.14159265
T the upper diameter
B the lower diameter
H the height of the truncated cone
```
##### Conversions
```one cubic inch (in³) = 0.000578703703703704 cubic feet (ft³)
one cubic inch (in³) = 0.000016387064 cubic metres (m³)
one cubic inch (in³) = 0.00432900432900432 gallons (gal) US
one cubic inch (in³) = 0.00360465014990905 gallons (gal) Imperial
one cubic inch (in³) = 0.016387064 litres (L)
