For a regular square pyramid with base perimeter 40 and slant height 50, what is the lateral and surface areas? |
Nick,
If the base is a square and you know the perimeter, what is the "base length" of each triangular side?
If the slant height is 50, what is the "height" of the triangle (taken two-dimensionally)?
The area of a triangle is half the base times the height. So what is the surface area of this pyramid?
