# Truncated Funnel Volume and Surface - Metres

Calculate the volume and surface area of a truncated funnel tank or container.
The funnel tank here has the shape of an upside down truncated cone with the bottom section cut off perpendicular to the top. This calculator uses metres for measurements.

##### Approximate weight of Fuel or Water

#### Calculator

1. enter the top diameter (T) of the funnel tank in metres
2. the bottom diameter (B) in metres
3. the height of the funnel tank in metres
4. the weight of the liquid in kilograms per litre

#### Results

1. the volume of the tank in cubic metres
2. the volume in cubic centimetres
3. the volume in cubic inches
4. the volume in cubic feet
5. the capacity of the tank in litres
6. the capacity in hectolitres
7. the capacity in US gallons
8. the capacity in Imperial gallons
9. full tank liquid weight based on kilograms/L
10. the surface area of the tank in square metres
11. the surface area in square centimetres
12. the surface area in square inches
13. the surface area in square feet

##### 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

```

```one cubic metre (m³) = 1000000 cubic centimetres (cm³)
one cubic metre (m³) = 61023.7440947323 cubic inches (in³)
one cubic metre (m³) = 35.3146667214886 cubic feet (ft³)
one cubic metre (m³) = 1000 litres (L)
one cubic metre (m³) = 10 hectolitres (hl)
one cubic metre (m³) = 264.172052358148 gallons (gal) US
one cubic metre (m³) = 219.969248299088 gallons (gal) Imperial
one square metre (m²) = 10000 square centimetres (cm²)
one square metre (m²) = 1550.0031000062 square inches (in²)
one square metre (m²) = 10.7639104167097 square feet (ft²)
