Asquare pyramid is shown. what is the surface area?

Area of a triangle equals 1/2 Bh

base = 2.5 height = 5

2.5 x 5 = 12.5/2 = 6.25

since there are 4 sides you multiply by 4

6.25 x 4 = 25

Now to do the bottom you multiply 2.5 x 2.5 = 6.25

6.25 + 25 = 31.25<ANSWER

step-by-step explanation:

well if you round, things become much more simple. round 5.95 to 6, 4.25 to 4, and 1.05 to 1. now, add 6+4+1 and that would equal 11. so the items together would equal to about $11.
