2. Hello, dianageo!

Given the values of lenght, width and height, find the length of diagonal AB.

(1) L = 9, W = 2, H=6

(2) L = 12, W = 8, H = 9

I will settle with the formula.

I assume these are rectangular boxes and we want the "space diagonal."

The formula is: . $d \;=\;\sqrt{L^2 + W^2 + H^2}$
