Diagonal of a Rectangular Prism
length L=+3
width W=+1
height h=2+
Step 1. Find the diagonal length of the base using the Pythagorean Theorem. Let's call this (A)
A%5E2=L%5E2%2BW%5E2
A%5E2=3%5E2%2B1%5E2
A%5E2=10
A=sqrt%2810%29
Step 2. Use this length of the base ( A ) with the height, and the Pythagorean Theorem to find the diagonal D of a rectangular prism
D%5E2=A%5E2%2Bh%5E2
D%5E2=%28sqrt%2810%29%29%5E2%2B2%5E2
D%5E2=10%2B4
D%5E2=14
D=sqrt%2814%29
