The total surface area of the eraser can be calculated by finding the area of each face and adding them together.
The front and back faces are each triangles with a base of 2 units and a height of 3 units. The formula for the area of a triangle is (1/2) x base x height.
The area of each triangle is (1/2) x 2 x 3 = 3 square units.
The top and bottom faces are each rectangles with a length of 2 units and a width of 3 units. The formula for the area of a rectangle is length x width.
The area of each rectangle is 2 x 3 = 6 square units.
The total surface area is the sum of all the areas: 3 (front) + 3 (back) + 6 (top) + 6 (bottom) = 18 square units.
Therefore, the total surface area of the eraser is 18 square units.
