Answer 10

For example, lets say that this prism is a rectangular prism, then the cross section's area would be the area of the traingle. And it will have the same cross section all along its length.

Answer 11

yep

Answer 12

So
the area of the cross section times the length = volume of the prism

Answer 13

and they told us

area of the cross section = 45
volume = 405

Answer 14

please can you add the values on the diagram so its easier for me to visualise
