When this net is assembled, it will form a box. To calculate the area of the outside surface, find the area of each section and add them together. The formula for area of a rectangle is A=lw:
A1=4(2)=8
A2=4(3)=12
A3=4(2)=8
A4=2(3)=6
A5=4(3)=12
A6=2(3)=6
8+12+8+6+12+6=52
The area that was painted green is 52cm2.
Hope this helps!!
