Answer:

27

Step-by-step explanation:

Since were finding the surface area we need to know the formula for area of a square and a triangle, to start with, a triangle area formula is length x width divided by 2 so aka 3x3/2= 4.5 and since there are 4 triangles, we can multiple 4.5 by 4 which gives us 18 and you add that by the area of the square which is length x width or 3x3= 9, your final answer is 18+9= 27

Answer:

SA = 2bs + b2

SA = 2 (3)(3) + (3)2

SA = 2 (9) + 9

SA = 18 + 9

SA = 27 cm2
