The total surface area of a rectangular prism is found by adding together the areas of all the faces.
Given that the prism has four sides, we need to find the fourth side in order to calculate the total surface area.
Let the unknown side have an area of x in.2.
The total surface area is as follows:
6 + 12 + 9 + x = Surface Area
27 + x = Surface Area
As the total surface area is unknown, there are no calculations that can be completed to determine a final answer.
Therefore, the total surface area of Jillian's prism cannot be determined with the given information.
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 prism?(1 point)
