Answer:

A) SA = 384 in²

Step-by-step explanation:

Equation for the surface area of a right pyramid: SA = B + 0.5Pl, where

  • B = area of the base
  • P = perimeter of the base
  • l = lateral height

1. Find the perimeter of the square: since the area is 144 in², the side length is √144 in, which is 12 in. This means that the perimeter is 48 in.

2. Plug in: SA = 144 in² + 0.5(48 in)(10 in)

3. Multiply: SA = 144 + 240

4. Add: SA = 384 in², which is A
