Use the net to find the surface area of the square pyramid. A)
130 in 2
B)
204 in?
C)
272 in2
D)
304 in 2

  D)  304 in^2

Step-by-step explanation:

The relevant area formulas are ...

  A = 1/2bh . . . . area of a triangle with base b and height h

  A = s^2 . . . . . . area of a square with side s

__

The figure consists of four identical triangles with base 8 and height 15. The area of each one is ...

  A = (1/2)(8)(15) = 60

The square has side length 8, so its area is ...

  A = 8^2 = 64

The total area of the figure is ...

  4(60) +64 = 304 . . . . square inches
