A rectangle ice cream was prepared with length 6cm, thicknes 2cm, height 5cm. if the volume of the ice cream was reduced by 19% and thickness remained the same , and height and length was reduced by same %. Then what is the new height?

• ans:4.5cm
  volume=6*2*5=60
  new volume=81% of 60=48.6
  let height and length are now x% of previous
  new volume=2*(x/100)*5*(x/100)*6=48.6
  x=90
  new height =90% of 5=4.5

• let length and is reduced by x%
  then (6-x*6/100)*(5-5*x/100)*2=60-(60*19/100)
  then after solving x=4.6,
  length=5.274,height=4.77....
