To find the total surface area of the prism, we need to add up the areas of all the faces.
Given:
- First face area = 6 in^2
- Second face area = 12 in^2
- Third face area = 9 in^2
Let's denote:
- First face area = A
- Second face area = B
- Third face area = C
Total surface area = 2A + 2B + 2C
Total surface area = 2(6) + 2(12) + 2(9)
Total surface area = 12 + 24 + 18
Total surface area = 54 in^2
Therefore, the total surface area of Jillian's prism is 54 in^2.
Jillian draws a net for a rectangular prism. One face of the prism has an area of 6 in.2 . A second face has an area of 12 in.2 , and a third face has an area of 9 in.2 . What is the total surface area of Jillian’s pri
