Answer:

240in

Step-by-step explanation:

Total surface area of a square based pyramid is expressed as

TSA = 1/2pl + B

p is the perimeter of the base

p = 4L

p = 4(2)

p = 8in

l = 4in

B is the base area = 2 * 2 = 4in^2

TSA = 1/2 * 8 * 4 + 4

TSA = 16 + 4

TSA of one game piece = 20in

Since we have 12 game pieces, total surface area will be 20 * 12 = 240in
