Answer:
Dividing by 3 means splitting a number into 3 numbers, all equal. The division sign can be represented by a /.
For example, 12/3=4. We can check our answer by multiplying our answer by 3, and seeing if we get our original answer.
4*3=12
Division is the opposite of multiplication, so it makes sense that multiplication is a valuable tool to check our work.

The temperature started at 15 degrees.
It dropped 25 degrees.
Subtract 25 from 15:
15 - 25 = -10
The temperature was -10 degrees.
Step-by-step explanation:

If the side lengths of B are 2x as long as the side lengths of A then the volume of B should be the volume of A^2
216^2=46,656
46,656-216=46,440
This can be more easily displayed with smaller numbers
If cube X were 2*2*2 then the volume would be 8
If cube Y were 4*4*4 then the volume would be 64
8(volume of cube X)^2=64(volume of cube Y)
