Question

A rectangular box has a length of 12 inches and a width of 4 inches. The length of the three-dimensional diagonal of the box is 14 inches. What is the height of the box?
I would like to see how to get this answer so I would like a formula or a equation for me thanks!!

Answer 1

Since it is a three dimensional diagonal

Then It is a rectangular prism

Where
D²=l²+w²+h²
14²=12²+4²+h²

h²=14²-(12²+4²)

Answer 2

thanks y'all
