Answer:
136 cm²
Step-by-step explanation:
I'm going to split the net into:
2x 7 cm by 2 cm rectangles
2x 6 cm by 7 cm rectangles
2x 6 cm by 2 cm rectangles
The 2x means there's 2 of them.
Let's find the area of the 2x 7 cm by 2 cm rectangles:
2*7*2=
4*7=
28 cm²
Let's find the area of the 2x 6 cm by 7 cm rectangles:
2*6*7=
2*42=
84 cm²
Let's find the area of the 2x 6 cm by 2 cm rectangles:
2*6*2=
12*2=
24 cm²
Adding all these areas together gives us the surface area of the net:
28+84+24=136 cm²
