Ok, so
Here we have a rectangular prism with the following measures:
-Length = 4ft
-Height = 3ft
-Width = 3ft.
Remember that the surface area of a rectangular prism can be found using:
Where "l" is the length, "w" is the width, and "h" is the height.
If we replace our values in the equation given, we got that:
Therefore, the surface area of the prism is 66 ft2.
