The length, width and height of a rectangular box are consecutive integers, and the largest dimension is k cm.

Question

how do you get an answer?

Answer 1

Largest is k, so the other 2 must be k-1 and k-2 for them to be consecutive. You didn't mention what the questions was, I'll assume it's:

What is the volume of a rectangular box whose sides are consecutive integers, and the largest dimension is k cm.

The volume is k*(k-1)*(k-2)=(k^2 - k)*(k-2)

=k^3 - 3k^2 + 2*k cm^3
