The Rectangular Prism Surface Area Calculator is a basic tool in geometry that helps us understand how much space the outer surface of a three-dimensional object covers. Let’s break down the formula, see what the letters mean, and understand why calculating total surface area matters in different areas.

## Total Surface Area of a Rectangular Prism Calculator

**Formula & Variables**

The Rectangular Prism Surface Area Calculator uses a simple formula:

$\mathrm{}\mathrm{}\mathrm{}$

**Variables:**

**SA (Total Surface Area):**This is like the total space the outside of the prism takes up, measured in square units.**l (Length of the Prism):**It’s the length of one side of the rectangular prism, measured in units.**w (Width of the Prism):**It’s the width of one side of the rectangular prism, measured in units.**h (Height of the Prism):**It’s the height of the rectangular prism, measured in units.

**How to Use the Calculator? **

Just a few easy steps:

**Calculate Areas of Individual Faces:**- $2lw$ for the length-width faces.
- $2lh$ for the length-height faces.
- $2wh$ for the width-height faces.

**Sum of Individual Face Areas:**- Add the areas calculated in step 1 together. $$
