Question

Compare the dimensions of the prisms. How many times greater is the surface area of the red prism than the surface area of the blue prism?

Answer 1

Answer: 9

Explanation: The surface area of the blue prism is 52, and the red prism is 468, if we divide 468 by 52, we get 9, so the red prism is 9 times greater than the blue prism's surface area.

Answer 2

9

Explanation:

12 m / 4 m = 3

6 m / 2 m = 3

9 m / 3 m = 3

The scale factor from the small prism to the large prism is 3.

The ratio of the areas is the square of the scale factor.

3² = 9

Answer: 9
