You just need three numbers that multiply to make 48. Because the volume of a rectangular prism is abh.
1 1 48
2 1 24
3 1 16
4 1 12
6 1 8
2 3 8
2 2 12
2 4 6
3 4 4
3 2 8
etc
Answer:
k = 11b - 8 (easiest to understand)
extra:
k = -8 + 11b
or
11b = -8 - k
etc. ( anything mixing up the components of the equation ).
