For this problem, we are told that the volume of a rectangular packing container is v of lwh equals l l times w times h cubic feet, where the length l, the width w and the height, h of the container, are all measured in feet.
00:14
In part a, we are asked to draw an input -output diagram for v.
00:18
So we have our inputs, l in feet, w in feet, and h in feet.
00:27
Little arrows indicating that they're going into our magic box, which is labeled v, and out comes v of l -w -h, which equals l times w times h in cubic feet.
00:49
Then for part b, we are asked to write a sentence interpreting v of 210 .5.
00:56
So i've done that ahead of time here.
00:58
V of 2 .1 .0 .5 is the volume when the container is two feet long, one feet wide and 0 .5 feet tall...
