The total surface area of the pencil sharpener can be calculated by finding the area of each surface and then adding them all together.

The pencil sharpener has 6 faces. Two of the faces have dimensions 5.77 x 6, two faces have dimensions 6 x 6.5, and two faces have dimensions 5.77 x 6.5.

The total surface area is:
(5.77 x 6) + (5.77 x 6) + (6 x 6.5) + (6 x 6.5) + (5.77 x 6.5) + (5.77 x 6.5) = 34.62 + 34.62 + 39 + 39 + 37.505 + 37.505 = 222.25

Therefore, the total surface area of the pencil sharpener is 222.25 square units.
it should have 2 decimal places
Apologies for the oversight. Rounding to two decimal places, the total surface area of the pencil sharpener is 222.25 square units.
