To find the surface area of a pyramid, we need to find the area of all the faces and add them up.
4 * 6 = 24
24 / 2 = 12
There are four sides (not including the base) in this pyramid, so we should multiply this by 4.
12 * 4 = 48
Now, we find the area of the base.
6 * 6 = 36
We add up all of the numbers:
48 + 36 = 84
84 in^2 is the answer.
Hope this helps!
