Answer:
33 units²
Step-by-step explanation:
From the net, we can see that the surface area consists of four triangles and one square:
Surface area = 4(area of triangle) + (area of square)
The base of the triangles (b) = 3, and their perpendicular height (h) = 4.
Area of triangle = (1/2)bh
Area of triangle = (1/2)(3)(4)
Area of triangle = 6
The square has side length (L) 3.
Area of square = L²
Area of square = 3²
Area of square = 9
Surface area = 4(area of triangle) + (area of square)
Surface area = 4(6) + (9)
Surface area = 24 + 9
Surface area = 33
