What is the surface area of the given rectangular prism with the dimensions of l=6 w=3 h=12?
The surface area of a rectangular prism can be found by adding up the areas of all six faces.
Each of the two rectangular faces (length x width) has an area of 6 x 3 = 18 square units.
The four remaining rectangular faces (height x width) have an area of 12 x 3 = 36 square units each.
Adding all six face areas together, we get:
18 + 18 + 36 + 36 + 36 + 36 = 180
Therefore, the surface area of this rectangular prism is 180 square units.
