If y is inversely proportional to x³, it means that the product of y and x³ is a constant. We can express this relationship as y = k/(x³), where k is the constant of variation.

Given that y = 8 when x = 2, we can find the value of k by substituting these values into the equation:

8 = k/(2³)
8 = k/8
k = 8 * 8 = 64

Now that we know k = 64, we can find the value of y when x = 4:

y = 64/(4³)
y = 64/64
y = 1

So, the value of y when x = 4 is 1.

If y is inversely proportional to x³, it means that the product of y and x³ is a constant. We can express this relationship as y = k/(x³), where k is the constant of variation.

Given that y = 8 when x = 2, we can find the value of k by substituting these values into the equation:

8 = k/(2³) 
8 = k/8
k = 8 * 8 = 64

Now that we know k = 64, we can find the value of y when x = 4:

y = 64/(4³)
y = 64/64
y = 1

So, the value of y when x = 4 is 1.
