The dimensions of a certain machine are 48" X 30" X 52". If the size of the machine is increased proportionately until the sum of its dimensions equals 156",what will be the increase in the shortest side?

• sum of dimensions now = 48+30+52 = 130'
  Increased sum of dimensions = 156'
  increased smallest side = 156*30/130 = 36 "
  
  increase in smallest side = 36-30= 6"

• 48+30+52=130, then 156-130=26
  the "proportionately" in the shortest side means 30/130*26=6"

• Let dimentions increase in proportion of x
  48x+30x+52x=156
  so, x=1.2
  smallest is 30 * 1.2=36
  increase is 36-6=30
