Where B is the area of the base 
P is the perimeter of the base

is pretty much what you have

take a look at one face, the bottom/base is 10, going upwards, is really just a triangle

jdoe0001 · Answer

get the area of THAT triangle, now you have 4 sides, thus 4 triangles, add all those up

then add the bottom/base, which is just a 10x10 rectangle
