If you want to know how much water a certain tank can hold, you need to calculate the volume of that tank. The rectangular prism calculator will help you determine the volume of any rectangular tank, while the cylindrical tank formula can be used for any type of cylindrical vessel. The capsule and elliptical tanks are useful if you’re trying to find out how much fluid would fit into a round or oval-shaped container, while frustum tanks are ideal when working with truncated cones – both cone bottom tanks and cone top tanks can be found using these formulas!

Take a look other related calculators, such as:

## Tank volume calculator

Use this calculator to determine how much water your would-be aquarium can hold. The calculator should be used for spherical, cylindrical, rectangular, elliptical, cone, and frustum tanks. It should also be used for tanks with cone bottom and cone top.

## Cylindrical tank volume formula

The formula for cylindrical tank volume is

V = π \times r^2 \times h

Where V is the volume of a cylinder, r is the radius of the cylinder and h is its height. To find this value, you first determine how much space there is inside your tank by measuring its diameter (D) and height (H).

## Rectangular tank volume calculator (rectangular prism)

The volume of a rectangular prism is the area at the base times the length by the width.

The volume of a rectangular prism with a sloping front is calculated by slicing off an appropriate part from one side, then multiplying that area by its height and adding it to the rest of the volume.

The volume of a rectangular prism with a curved front is calculated by slicing off an appropriate part from each end, then multiplying those areas by their heights and adding them together.

## Elliptical tank volume (oval tank)

The elliptical tank volume calculator is a tool that allows you to easily find the volume of an elliptical aquarium or oval aquarium. This result can then be used to help determine your tank’s capacity based on the dimensions of your housing.

To use the calculator, enter the dimensions of your elliptical (oval) tank followed by its height and weight. The calculator will use algebraic equations to determine its volume while also providing a few helpful tips on how best to utilize this information in order to make better decisions about what types of animals would best fit into your new home!

## Frustum volume – tank in the shape of a truncated cone

The frustum of a cone is the part of a cone that remains when its top has been cut off. It’s usually represented as a triangle with the same height as the original cone but with half the radius of its base, since cutting off that top means you’ve halved your volume.

The formula for calculating this truncated form is easy enough to remember: it’s just one-half times pi times r squared, where r is your original radius and h is your new height (in other words, if you have an 8-foot diameter tank and want to know how tall it needs to be so that it can hold all of your fish, then take half pi times 8 x 8).

As mentioned above though – different shapes require different types of calculations; however, most things can be broken down into simple parts (like cones) which make them easier to figure out and calculate

## Cone bottom tank volume (conical tank) and cone top tanks

A cone bottom tank, also known as a conical tank, is a cone with a circular base. This type of water storage container can be used for storing water in a home or business. The sides of the tank are usually slanted and have vertical walls that reach the top of the container before connecting to each other. Cone bottom tanks are often shaped like cylinders but they are not considered cylindrical because they taper down at the end rather than being flat across their entire surface area like an actual cylinder would be.

Cone top tanks have flat tops instead of sloped ones, which means they have more usable space inside them than cone bottom tanks do

## FAQ

### How much volume is a liter?

Cubic meters and liters are two common metric units of volume. 1 cubic meter is 1000 liters.

### What is the capacity of a fish tank?

Fish tanks can range in capacity from just 0.5 gallons to over 200 gallons.

### What size tank do I need for 2 goldfish?

If you have two common goldfish, a tank of 50-60 is the ideal size. Try to aim for a tank with more water surface area than depth, because goldfish prefer longer tanks.
