Student:Sorry, that's not right. It looks like you squared the edge length, but you needed
to cube it (4 * 4 * 4 = 64). In problems like these, it helps to check
the rule you've come up with against all the pairs of numbers.
-
Teacher:Looks like the student did 4 * 4, and forgot the last multiplication.
- Observable: 36.

-
Student:Sorry, that's not right. It looks like you multiplied the edge length by 9, but you needed
to cube it (4 * 4 * 4 = 64). In problems like these, it helps to check
the rule you've come up with against all the pairs of numbers.
-
Teacher:Looks like the student looked at the relationship between edge length=3 and
volume=27, but didn't check it against the other numbers.
- Observable: 32.

Student:Sorry, that's not right. It looks like you multiplied 4 * 8, but you needed
to cube the side (4 * 4 * 4 = 64). In problems like these, it helps to check
the rule you've come up with against all the pairs of numbers.

-
Student:Sorry, that's not right. To solve problems like this, you need to find the edge length
and then cube it. For this problem, the edge length is 4, so 4 * 4 * 4 = 64 (the volume).
