Enter the volume when the edge length of a cube is 4 (A in the table):
The volume of the three cubes above is shown in the table below.
| Edge Length |
Volume |
| 1 |
1 |
| 2 |
8 |
| 3 |
27 |
| 4 |
A |
Enter the value for A:
64
Correct, good job!

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.
Looks like the student did 4 * 4, and forgot the last multiplication.

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.
Looks like the student looked at the relationship between edge length=3 and
volume=27, but didn't check it against the other numbers.

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.

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).
