8 times bigger, 112 ounces

anonymous · Answer

the area of a box is x,y,z multiplied together, if you double those, 2x,2y,2z, it's a factor of 8 times larger.

if the dimensions of the original box are L, B and H
then volume = L*B*H = LBH = 14 oz   ------- (1)

on doubling the dimensions we have 2L, 2B, 2H

so volume = 2L*2B*2H = 8 LBH = 8*14  {using (1)}
                                                      = 112 oz
