Given that:
- The desk is 80 centimeters wide at the front.
- It is 60 centimeters wide at the back.
- It is 50 centimeters deep.
You can conclude that it is a rectangular prism.
The Surface Area of the rectangular prism can be calculated using this formula:
Where "l" is the length, "w" is the width, and "h" is the height.
In this case, you can set up that:
![\begin{gathered} l=80\operatorname{cm} \\ w=60\operatorname{cm} \\ h=50\operatorname{cm} \end{gathered}]()
Therefore, substituting values into the formula and evaluating, you get:
![SA=2(60\operatorname{cm})(80\operatorname{cm})+2(50\operatorname{cm})(80\operatorname{cm})+2(50\operatorname{cm})(60\operatorname{cm})]()
Hence, the answer is:
