A shipping company charges per cubic inch to ship a package. Which of the boxes is the MOST expensive to ship. Please see attachment. Box a is incorrect.

Answer:
B. Box B
Step-by-step explanation:
Which ever box's volume is the largest, that box would cost the most.
The volume of a rectangular box is length * width * height
Let's find the volumes of each of the boxes:
1. Box A Volume = 10.5 * 12 * 4.5 = 567 cu. in.
2. Box B Volume = 8.5 * 8.5 * 8.5 = 614.125 cu. in.
3. Box C Volume = 10.5 * 8.5 * 6.5 = 580.125 cu. in.
4. Box D Volume = 12 * 6.5 * 6.5 = 507 cu. in.
We can clearly see that Box B has the largest volume. Hence, Box B is the most expensive to ship.
Answer:
Step-by-step explanation:
The only way I know to do this is to try them all.
Formula
V = length * width * height
V = l * w * h
Solution
A]
V = 12 * 10.5 * 4.5 =
V = 567
B]
V = 8.5^3
V = 614
C]
10.5 * 8.5 * 6.5
580
D]
V = 12*6.5 * 6.5
V = 507
Conclusion
B would be the most expensive to ship.
