Answer 3

the surface area of the square prism equals the areas of the four faces
the are of one face= 4 times 12 = 48
the surface area of the square prism= 4 times 48= 192
the surface area of the pyramid= 4 times the area of the four triangles
you could do that
and then add what you got from the last step to 192 and u will get the answer
