To calculate the surface area of a sphere, you first need to determine its radius. Once you know the radius, you need to square it, or multiply it by itself. Next, you will need to multiply it by 4. Finally, you will multiply that number by pi, or 3.14.
You multiply the number by itself.
all you do is multiply a number x a number = the square!

There is no standard formula since a polyhedron can have a number of different shapes. A hexahendron, for example, can be a cuboid (6 rectangular faces) or a triangular dipyramid (6 triangular faces) or others. The number of different shapes increases rapidly as the number of sides (which determines the name) increases. The only solution is to calculate the area of each face and add them together.
