Answer:
The area of enlarged prism is 4 times surface area of original prism.
Explanation:
We have been given that a rectangular prism has a height of 8 cm, a length of 4 cm, and a width of 3 cm. The prism is enlarged by a scale of 2.
Let us find total surface area of original prism as:





Since the prism is enlarged by a scale of 2, so each side of new prism would be 2 times grater than side of original prism as:
Length: 8 cm
Width: 6 cm,
Height: 16 cm.



Let us find ratio of surface area of the enlarged prism to the original prism as:


Therefore, the area of enlarged prism is 4 times surface area of original prism.
