# Step-by-Step Guide to Calculate the Length of a Box's Diagonal

As a developer, you may find it difficult to remember the steps to calculate the diagonal length of a box. Knowing how to properly calculate a box's diagonal is an important skill to possess, as it is often required when measuring a box for shipping purposes. This guide will provide you step-by-step instructions on how to calculate the length of a box's diagonal, making it easier for you to measure a box quickly and accurately.

## Step 1: Gather the Necessary Information

The first step is to gather the necessary information to calculate the diagonal length. Specifically, you will need the length and width of the box. If you do not have the necessary information, use a ruler to measure the box's length and width so they can be used in the calculation.

## Step 2: Calculate the Diagonal Length Using the Pythagorean Theorem

Once you have the necessary length and width measure this, you can calculate the diagonal of the box using the Pythagorean Theorem. The Pythagorean Theorem states that “the sum of the squares of the lengths of the two sides of a right triangle is equal to the square of the length of the hypotenuse.”

To apply this to figuring out the diagonal length, you will square the length and width of the box, add them together, and then take the square root of the answer. This number is the diagonal length of the box.

## Step 3: Record the Diagonal Length

Once you have found the diagonal length of the box, record it somewhere safe, such as in a spreadsheet or on a piece of paper. This number is vital for shipping purposes, so it is important to record it and keep it somewhere safe.
