if all sides of a cube are reduced by 1/2, how does it affect volume?

a. decreases 200%
b. decreases 400%
c. decreases 800%
d. decreases 600%

answer b

  • math -

    Nothing can decrease more than 100%. At that point, it is all gone.

    If the new side is 1/2 the old side, the volume is 1/8 the old volume.
    That is NOT the same as decreasing by 800%. The volume decreased by 7/8, or 87.5%.

    this answer is logically wrong
