How do you solve the following problem?
A cube has a volume of 512 cubic centimeters.
SA e
V e
=
=
6× 2
3
If the cube is completely covered with wrapping paper, what is the minimum amount of paper
needed to cover all 6 faces?

How do you determine if there is a proportional relationship in a function table? Is there some way to determine the rule by just evaluating the table of x and y values?

Sorry, I copied question and pasted. There is a box with a hint. It states that SA= 6 x e2 and V= e3, sorry I can't convert to exponents on this computer. So, given the V= 512 cc, how do I determine the minimum amount of paper needed to cover the box?

Thanks, I have it!

Help! I don't understand this question.

Which of these relations is a function?

1. {0,1} {1,2} {2,4}
2. {0,1} {0,2} {0,3}
3. {0,1} {1,2} {1,4}
4. {0,1} {0,2} {2,4}

Thanks! I understand!

How do I set up this problem to solve? I have read the entire tutorial, and still don't understand. On Friday, the students in a physical education class were allowed to play either soccer or basketball. The ratio of students playing soccer to students playing basketball on Friday was 4:1. What perc...

Thanks!
