Answer:

The volume of the shipping box is
V=27\ in^3

Explanation:

see the attached figure to better understand the problem

The volume of the triangular prism is equal to


V=BH

where

B is the area of the triangular base

H is the height of the prism

In this problem we have


H=9\ in

Find the area of the triangular base B


B=(1)/(2)bh

we have


b=3\ in\\h=2\ in

substitute


B=(1)/(2)(3)(2)=3\ in^2

Find the volume of the triangular prism


V=BH

we have


B=3\ in^2


H=9\ in

substitute


V=(3)(9)=27\ in^3
