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 equals 4.5 cm, with equals 3.5 cm, and high equals 2.5 cm. One point.
The surface area formula for a right rectangular prism is:
Surface area = 2(length x width) + 2(length x height) + 2(width x height)
Plugging in the given measurements:
Surface area = 2(4.5 cm x 3.5 cm) + 2(4.5 cm x 2.5 cm) + 2(3.5 cm x 2.5 cm)
Surface area = 2(15.75 cm²) + 2(11.25 cm²) + 2(8.75 cm²)
Surface area = 31.5 cm² + 22.5 cm² + 17.5 cm²
Surface area = 71.5 cm²
Therefore, the surface area of the shape is 71.5 cm².
