Volume and Surface Area

Find the exact surface area and volume of a right square pyramid with a radius of 2 inches and a height of 6 inches.

  • Volume and Surface Area -

    Does a pyramid have a radius?

  • Volume and Surface Area -

    Volume of any right pyramid:

    1/3 areabase*height

    Surface area depends on the shape.
    area base + area of all sides

    That's what I'm confused about.
    The question that my teacher assigned clearly said "radius" and I'm not sure if I can apply that term as a "side".

  • Volume and Surface Area -

    Can I assume that the radius is the same as a side? Or do I double it?

    Apparently, your teacher had a brain freeze on writing the problem. If it were me, I would work it as "side", and say so, and why. Sometimes teachers err.
