Question 3 • *22SS - 1207350 - Mathematics for College Liberal Arts - Sem. 2 - CR

A cube has a side length of 10 cm. The cube is dilated by a scale factor of 5. How does the volume of the new cube compare to the volume of the original cube?

Answer
A
The volume of the new cube is equal to the volume of the original cube.
B
The volume of the new cube is 5 times the volume of the original cube.
C
The volume of the new cube is 25 times the volume of the original cube.
D
The volume of the new cube is 125 times the volume of the original cube.

Explanation

A dilation multiplies each side length by 5, so the new cube has side length 10 × 5 = 50 cm. Volume scales by the cube of the scale factor: 5³ = 125. Therefore, the new cube’s volume is 125 times the original volume, which is choice D.
