Answer:
The surface area of the prism is 96 cm²
Explanation:
What is surface area? Surface area is the sum of the areas of all the faces (or surfaces) of a three-dimensional object. The length and width of the rectangular face are 4.5 cm and 3 cm, respectively, so the area is:4.5 cm x 3 cm = 13.5 cm²Since there are two rectangular faces on the prism, the total area for the pair is:= 2 x 13.5 cm² = 27 cm²Similarly for the another face3 cm x 3 cm = 9 cm²Since there are two square faces on the prism, the total area for the pair is:= 2 x 9 cm² = 18 cm²The area of one of the rectangular faces that is not congruent to the first two:= 8.5 cm x 3 cm = 25.5 cm²Since there are two rectangular faces that are not congruent to the first two, the total area for the pair is:= 2 x 25.5 cm² = 51 cm²Now we can find the total surface area by adding the area of each pair of faces:= 27 cm² + 18 cm² + 51 cm² = 96 cm²Therefore, the surface area of the rectangular prism is 96 square centimeters.
