Question 1050236: I need help on writing polynomial expressions of the volume and surface areas of some figures. I've already tried what I can (we didn't cover this well in class so I'm lost).
1) Rectangular prism. Length = 3b; width = b+1; height = b-5
2) Cone. Height = 12n; radius = n-2
3) Pyramid. Lenght = k-2; width = 2k+3; height = 3k
4) Rectangular prism. Length = 2x+1; width = x+3; height =2x
5) Cylinder. Height = w+3; radius = w-1
6) This last one is a 3D triangle...forgot what it's called. Height = 2y; width = 2y+1 ; length = 3y; the sloping thing is y+3
Please help, I really need to figure out how to do this as we didn't do this well in class and I don't understand.

On surface area and volumes of solid bodies see the lessons
    - Surface area of 3D solid bodies
    - Volume of 3D solid bodies
in this site.

The links in these files will lead you to the real lessons.

These lessons are the basics.

If you know basics well, you can solve everything.

If you do not know basics, you can solve nothing.
