Describe one real object with the given shape. Explain why you might want to find the volume of the object.
Triangular prism


A roof

Yes. It also looks like a pup tent to me.
I can think of reasons to want to figure the volume of an attic/ roof and also a pup tent. 
Could a reason to be like of you wanted to paint a roof you could find the volume to know how much paint you would need?

The volume wouldn't tell you what you needed to paint the roof. You'd need the area of the roof to find the amount of paint needed.
But if you consider the attic floor, then you might want to know the volume to find how much room you'd have to store stuff.
The volume of the tent would give you the cubic feet of space in the tent.
