    one face is equal to base times height divided by 2. to find the height of the face; you use the fact that 8 and 3 are the legs of another triangle with the hypotenuse of it being your surce height...does that make sense?

    SA would be Length x Width

    A square pyramid is just a square with 4 triangles on top of it. So take it step by step. A square has area side^2. A triangle has area (1/2)*base*height. There's 4 triangles, all with the same area. Add the (area of the square) + 4*(area of triangle)

    sqrt(64 + 9) = sqrt(73) the surface area of the entire pyramid, not counting the bottom is: 6sqrt(73)/2 times 4

    drop a perpendicular down the center and you get 8 for the height of the pyramid. measure over 3 from there to get a triangle of: 8^2 + 3^2 = r^2 and r is the "height" you use to figure for the face triangles. r = sqrt(64 +9) = sqrt(73) sqrt(73) times 6 for the base divided by 2 gives the area of 1 face. times that by 4 to get all the faces. include the bottom if need be :) 6*6 = 36
