The total surface area of the pencil sharpener can be calculated by adding the surface areas of each individual face.
Surface area of rectangular faces:
- Front and back faces: 6 cm * 15 cm = 90 cm² (2 faces)
- Top and bottom faces: 5.77 cm * 15 cm = 86.55 cm² (2 faces)
- Side faces: 6 cm * 5.77 cm = 34.62 cm² (2 faces)
Adding all the surface areas together:
90 cm² + 90 cm² + 86.55 cm² + 86.55 cm² + 34.62 cm² + 34.62 cm² = 332.34 cm²
Therefore, the total surface area of the pencil sharpener is 332.34 cm².
what is the total surface area of the pencil sharpener? Your answer should have twp decimal places.
Th numbers: 6 cm, 5.77 cm, 15 cm, and 6.5 cm.

Ther isnt any rounding in the problem
I apologize once again. The total surface area of the pencil sharpener, without rounding, is 332.34 cm². Thank you for pointing that out.
