Find the total surface area of the pyramid
quester [9]
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!
