Question 977268
Not at all precise a question.


Dimensions, x, y, z.
Let z be a constant value, k=z.
Let y be a function of x, {{{f(x)=ax+b}}}, for some constants a and b.


Now the volume will be {{{v=xyz=x*f(x)*k=x(ax+b)*k=kx(ax+b)=akx^2+bkx}}}.


Knowing the given value for volume,  {{{akx^2+bkx=270}}}.
