## Summary

To calculate the volume of a rectangular prism, you can use Excel's multiplication operator (*) with measurements for length, width, and height. In the example shown, the formula in E5, copied down, is:

``````=B5*C5*D5
``````

which calculates the volume of a rectangular prism, given the length in column B (l), the width in column C (w) and the height in column D (h). Units are indicated generically with "u", and the resulting volume is in units cubed (u3).

## Generic formula

``=l*w*h``

## Explanation

In geometry, the formula for calculating the volume of a rectangular prism is:

``````=lwh
``````

This formula can be represented in Excel with the multiplication operator (*) like this

``````=l*w*h
``````

In the example shown, the formula in E5 is:

``````=B5*C5*D5 // returns 0.13
``````

As the formula is copied down the column, it calculates a new volume in each row, using the length in column B (l), the width in column C (w) and the height in column D (h).
