Question
The postal service will accept a box for domestic shipment only if the sum of its length and
girth (distance around) does not exceed 99 in. Suppose that you have a box with square sides so
that its dimensions are h by h by w and the girth is 2h+2w, such a box is shown to the right.
Complete part (a) and (b).
a. What dimensions will give the box its largest volume?
b. Graph the volume as a function of h and compare what you see with your answer in part (a).
Girth (distance around here)
a. Let h denote the length of the box and w denote the width, set up the equation of the volume of the box, V.
v = ☐
When h=
inches and winches, the box has largest volume.
(Type integers or decimals.)
b. Choose the correct graph of the volume V as a function of h below.
