How the hexagon tank calculator works

This calculator computes the volume and capacity of a regular hexagonal tank using the formula: Volume = (3√3/2 × s²) × h, where s is the side length and h is the height. The area of a regular hexagon is (3√3/2) × s², which is then multiplied by the height to get the total volume.

Enter the side length, height, and choose your preferred unit (cm, m, inches, or feet). The calculator instantly shows the volume in cubic units, liters, US gallons, UK gallons, and the total surface area of the tank.

Understanding Hexagonal Tanks

A regular hexagon has six equal sides and six equal angles. The volume of a hexagonal tank is calculated by multiplying the area of the hexagon base by the height of the tank. This is a common shape for aquariums, fuel tanks, and storage containers.

Volume Breakdown

Hexagon Tank Formula

Volume = (3√3/2 × s²) × h

Where s is the side length of the hexagon and h is the height of the tank. The area of a regular hexagon is (3√3/2) × s², which is multiplied by the height to get the total volume.

Surface Area = 2 × (3√3/2 × s²) + 6 × (s × h) — this includes the top, bottom, and six rectangular side faces.

Frequently Asked Questions

How do you calculate the volume of a hexagonal tank?

The volume of a regular hexagonal tank is calculated using the formula: Volume = (3√3/2 × s²) × h, where s is the side length and h is the height of the tank.

What is the formula for the area of a hexagon?

The area of a regular hexagon is given by the formula: Area = (3√3/2) × s², where s is the length of one side. This formula comes from dividing the hexagon into six equilateral triangles.

How many liters does a hexagonal tank hold?

To find the capacity in liters, calculate the volume in cubic centimeters (cm³) and divide by 1,000. Or calculate in cubic meters (m³) and multiply by 1,000. The calculator above does this conversion automatically.

What is the surface area of a hexagonal tank?

The surface area of a hexagonal tank includes the base, top, and six rectangular sides. Total surface area = 2 × (3√3/2 × s²) + 6 × (s × h), where s is side length and h is height.

What units can I use with the hexagon tank calculator?

You can enter side length and height in centimeters (cm), meters (m), inches (in), or feet (ft). The calculator will show results in cubic units, liters, US gallons, UK gallons, and more.
