If the length of an edge of cube P is twice the length of an edge of cube Q, what is the ratio of the volume of cube Q to the volume of cube P?
Choose the correct choice from the following answers: A) 1/8 B) 1/4 C) 1/3 D) 1/7 E) 1/9
The length of cube Q = 1;   The length of cube P = 2;   The ratio of the volume of cube Q to the volume of cube P = 1^3/2^3 = 1/8.   1/8nswer: 1/8
