Given:
length=8.5 feet
Width=2 feet
height=3.5 feet
Solution:
volume of right rectangular prism=l*w*h
=8.5*2*3.5
=59.5
Content density=0.34 pound per cubic foot(Given in question)
Density=mass/volume
[tex]0.34=\frac{weight\text{ of the content in the container}}{59.5}[/tex][tex]\text{Weight of the content in the container=0.34}\times59.5[/tex][tex]\text{Weight of the conent in the container=20.23 pounds(to the nearest pound)}[/tex]
