The formula for the surface area of a right rectangular prism is:
Surface area = 2 * (length * width + length * height + width * height)
Substituting the given measurements:
Surface area = 2 * (4.5 cm * 3.5 cm + 4.5 cm * 2.5 cm + 3.5 cm * 2.5 cm)
Surface area = 2 * (15.75 cm² + 11.25 cm² + 8.75 cm²)
Surface area = 2 * (35.75 cm²)
Surface area = 71.5 cm²
Therefore, the surface area of the shape is 71.5 cm².
Use the formula for the surface area of a right rectangular prism to find the surface area of a shape with the following measurements: length = 4.5 cm, width = 3.5 cm, and height = 2.5 cm.(1 point)
