# Rectangular Tank Surface Area Calculator

This surface area of a rectangular tank can be calculated using our online rectangular tank surface area calculator. Besides the calculation tool, the calculator also shows and explains the rectangular tank surface area formula with an example.

## Rectangular tank surface area formula

If you want to calculate the surface area of a rectangular tank, you can use the formula:

`A = 2lw + 2lh + 2wh`

where `l`

is length, `w`

is width, and `h`

is height.

## Example of how to calculate the surface area of a rectangular tank

We know the rectangular tank surface area formula, and what’s next? Well, let’s solve an example problem with the formula.

For a rectangular tank with the length l = 4 cm, width w = 5 cm and height h = 7 cm, we can calculate its surface area like so:

`A = 2lw + 2lh + 2wh`

`A = 2 * 4 * 5 + 2 * 4 * 7 + 2 * 5 * 7 = 166 cm`
