The surface area of a rectangular prism A is 158 units2. If rectangular prism A is dilated by a scale factor of 2 to create rectangular prism B, what is the surface area of rectangular prism B?

Question

A.
316 units2
B.
632 units2
C.
1,264 units2
D.
79 units2

Answer 1

C. 1,264 units2

When a prism is dilated by a scale factor of 2, the surface area is multiplied by the square of the scale factor. In this case, the original surface area of prism A is multiplied by 2^2 = 4 to get the surface area of prism B. So, 158 units2 * 4 = 632 units2.
