Answer:
The volume of box Y is 1/64 of the volume of box X
Step-by-step explanation:
Since. The edge of a box Y is 1/4 the lengtj of box X ;
The volume is 3 dimensional and each dimension of Y is 1/4th the dimension of X
The volume of Y will be (1/4)^3 the volume of Y
(1/4)^3 = 1/4 * 1/4 * 1/4 = 1/64
For instance, if edge of X = 8
Edge of Y which is 1/X ; edge Y = 1/4(8) = 2
Volume, X 8^3 = 512
Volume Y = 2^3 = 8
8/512 = 1 / 64
