# How do I calculate my fish tank?

## How do I calculate my fish tank?

Using the surface area rule, the shape difference between the tanks is taken into account. The surface area is calculated by multiplying the width times the length of the tank. Under the water surface area rule, the tank can be stocked with one inch of fish for every twelve square inches of surface area.

## How much gravel do I need for 180l tank?

about 25 kilos

How much gravel do I need for my fish tank? Aquarium sand and gravel vary in weight and density, but if you aim for a two to three-inch layer, an average-sized 180 litre tropical aquarium will need about 25 kilos.

**How much gravel do I need for my fish tank calculator?**

Generally speaking, you should add about 1 pound of substrate per gallon of water. This means that for a 5-gallon fish tank, a safe bet would be 5 pounds of gravel. Similarly, for a 20-gallon fish tank, roughly 20 pounds of gravel would suffice.

**How many fish can I have in a 240 litre tank?**

So if you had say a 240 litre tank you could comfortably house around 40-50 tetras in there or other small community fish such as barbs or even livebearers. Don’t forget though that you are always likely to have your “core” fish such as the bristlenose pleco, this still counts in your allowance.

### What is a formula of cylinder?

Cylinder’s volume is given by the formula, πr2h, where r is the radius of the circular base and h is the height of the cylinder.

**How do you find the volume of a cylinder calculator?**

Calculate volume of a cylinder: V = πr2h.

**How do you calculate liters in a cylinder?**

OR Litres

- Cylinders have a volume in litres.
- To calculate the volume of a cylinder, use the following equation V = πr²h.
- The density of water is 1kg/litre so 1 litre = 1000cm^3.
- To convert to millilitres divide by 1000 (1000ml=1 litre)

## What is the formula for calculating volume of a cylinder?

V = πr2h

The volume of a cylinder with base radius ‘r’ and height ‘h’ is, V = πr2h. If its base diameter is d, then we have d = r/2. Substituting this in the above formula, we get V = πd2h/4. Thus, the formula to find the volume of a cylinder with the diameter (d) and height(h) is V = πd2h/4.

## How do you calculate the volume of a container?

The volume of a container is the amount of space it encloses; or how much space is inside of it. For a box, the volume is determined simply by this formula: A box with height H, width W and length L, has volume V = L × W × H.

So if you want to get an accurate estimate for the water volume in your aquarium, whether straight-lined, curved, or corner tank, then read on to find out how!

**How to calculate the volume of a cylindrical tank?**

This is simply the formula to calculate the volume of a cylindrical tank but divided by four. This formula calculates the area of a triangle before multiplying by the height. Again, to make things easier to measure, we ask you to include the full diameter and our calculator divides it by two to get the radius.
