Answer:
64 sq cm
Step-by-step explanation:
square area formula is length times width, so we multiply 4 x 4
4x4 = 16 square cm
triangle area formula is base x height x 1/2 (divide by two)
4 x 6 = 24 x 1/2 = 12
multiply 12 by four to account for all triangles
12 x 4 = 48
add both areas
16 + 48 = 64
The surface area of this net is 64 sq cm.
