Question

to find the space diagonal of a prism, you use the of the base and the height in the pythagorean theorem.

Explanation:

In the Pythagorean - related formula for the space diagonal of a prism, we use the diagonal of the base and the height. The three - dimensional Pythagorean theorem for a rectangular prism with length $l$, width $w$, and height $h$ for the space diagonal $d$ is $d=\sqrt{l^{2}+w^{2}+h^{2}}$, where $\sqrt{l^{2}+w^{2}}$ is the diagonal of the base.

Answer:

diagonal
