[Question]Justin has a box that is 12 inches in height. The length of the box is 3 times its height and 4 times its width. What is the volume of the box?
[Answer]The length of the box is 3 x the height of 12 inches = 36 inches. The width of the box is 36 inches / 4 = 9 inches. The volume of the box is the height of 12 inches x the length of 36 inches x the width of 9 inches = 3,888 cubic inches. The answer is 3888.

[Question]A man is returning home from work and trying to decide which route to take. His first route option includes 3 stoplights. This route will take him 10 minutes if all three lights are green, but each light that is red will add 3 minutes to the trip. The second route does not include any stoplights and takes 14 minutes. If the man chooses the first route, how much longer will his trip be if all 3 stoplights are red?
[Answer]If all 3 stoplights are red, the first route will take 10 + 3 * 3 = 19 minutes. Thus, the first route will take 19 - 14 = 5 minutes longer than the second route. The answer is 5.

[Question]Three cats sat on a fence, meowing at the moon. The first cat meowed 3 times per minute. The second cat meowed twice as frequently as the first cat. And the third cat meowed at one-third the frequency of the second cat. What is the combined total number of meows the three cats make in 5 minutes?
[Answer]The second cat meowed twice as frequently as the three meows per minute from the first cat, for a total of 2 * 3 = 6 meows per minute. The third cat meowed at one - third the frequency of the second cat, for a total of 6 / 3 = 2 meows per minute. Thus, combined, the three cats meow 3 + 6 + 2 = 11 times per minute. In five minutes, the three cats meow 5 * 11 = 55 times. The answer is 55.

[Question]Class A is twice as big as Class B. Class A is also a third the size of Class C. If Class B has 20 people in it, how many people are in Class C?
[Answer]
Class A is twice the size of Class B, so Class A = 2 * size of Class B. If Class B has 20 people Class A has 20 * 2 = 40 people. Since Class A is also 1 / 3 the size of Class C then Class A = 1 / 3 * Class C. This means 40 = 1 / 3 * Class C. Thus the size of Class C is 3 * 40 = 120 people. The answer is 120.
