The eraser can be visualized as a rectangular prism with dimensions 1.12 x 2 x 6 inches for three of its faces, and as a rectangular prism with dimensions 1.12 x 6 x 1.5 inches for the other three faces.
Calculating the surface area of each face:
- For the faces with dimensions 1.12 x 2 inches: 1.12 x 2 = 2.24 square inches each
- For the faces with dimensions 2 x 6 inches: 2 x 6 = 12 square inches each
- For the faces with dimensions 1.12 x 1.5 inches: 1.12 x 1.5 = 1.68 square inches each
Calculating the total surface area:
2 (2.24) + 2 (12) + 2 (1.68) = 4.48 + 24 + 3.36 = 31.84 square inches
So, the total surface area of the eraser is 31.84 square inches.
What is the total surface area of this eraser? Your answer should have two decimal places. measurements: 1.12 inches., 2 inches, 6 inches, 1.5 inches.
