The height if the smaller box is 80% of th height of thr larger box while the other two dimensions are the same for both boxes what is the difference in the volume of the two boxes

Let the height of the larger box = h and length and width of the larger box = l and w , repectivelyNow , Let find the volume of the larger boxVolume = length * width * heightSo Volume of the larger box = l*w*h = lwh
Now the question saysthe height of the smaller box is 80% of the height of the larger boxIt means Height of the smaller box = 80% of h = 0.80*h = 0.80hand the other two dimensions are same so it means length and width of the smaller box = l and w so, Volume of the smaller box = l*w*0.80h = 0.80lwh

So the Difference in the volume of the two boxes = Volume of larger box - Volume of smaller boxtherefore , Difference in the Volume of two boxes = lwh - 0.80 lwh = 0.20lwh
