Answer:
184 cm²
Step-by-step explanation:
You can find the surface area of this net by finding the area of each rectangle and adding them up.
The top rectangle has dimensions of 10 and 6. You multiply them to get 60. Add in the units and the area of the top rectangle is 60 cm².
The rectangle under the one we just found the area for has the dimensions 10 and 2. Find the area. A = 20 cm².
The two rectangles to the side of the second rectangle have the dimensions of 6 and 2. The area of one is 12 cm². This means the two rectangles added together are 24 cm².
The next rectangle has the same dimensions as the first rectangle we solved. Therefore, the area is the same, which is 60 cm².
The last rectangle has the same dimensions as the second rectangle we solved. Therefore, the area is the same, which is 20 cm².
We will add the numbers altogether to find the surface area.
60 + 20 + 24 + 60 + 20 = 80 + 24 + 80 = 104 + 80 = 184 cm²
