Question 1199716
<font color=black size=3>
L = length
W = width
H = height
volume = LWH


The length and width are decreased by 30%
They keep the remaining 70%
0.7L and 0.7W represent the new length and width respectively.
The height is doubled to go from H to 2H


new volume = (new length)*(new width)*(new height)
new volume = (0.7L)*(0.7W)*(2H)
new volume = (0.7*0.7*2)*(LWH)
new volume = (0.7*0.7*2)*(old volume)
new volume = 0.98*(old volume)
(new volume)/(old volume) = <font color=red size=4>0.98</font>


Interpretation: 
The new volume is 98% of the old volume
In other words, there is a 2% loss in volume.
It would be like going from 100 cubic inches to 98 cubic inches.
