Answer:
We can see from the net that there are two rectangles with dimensions 3 cm by 6 cm, two rectangles with dimensions 2 cm by 6 cm and two rectangles with dimensions 2 cm by 3 cm. The total surface area is then
2 × 3 × 6 + 2 × 2 × 6 + 2 × 2 × 3 = 72 cm2
Step-by-step explanation:
Answer:
The surface area is the area of all the squares/rectangles
multiply all the numbers to get the areas
2 x 3 = 6
3 x 7 = 21
2 x 7 = 14
6 + 14 + 21 = 41
there is two of each square so we multiply by 2
41 x 2 = 82
82 is the surface area
