Concept explainers
To determine the possible values of
The possible values of
Given the function representing the volume:
Concept Used:
The volume of a box crafted from a rectangular piece of material with length
Now, since
That is,
Also, the length of the material should not exceed 2 times
That is, the half-length of the material should not exceed
That is,
Finally, the width of the material also should not exceed 2 times
That is, the half-width of the material should not exceed
That is,
Concluding,
Calculations:
Equate
Compare the coefficients of
Solve the equation
Substitute
Solve the quadratic equation
Substitute
Substitute
That is, the length and width of the material are interchangeable.
Now, without loss of generality, let
Then, it follows that:
That is:
That is:
That is:
Thus, the possible values of x are:
Conclusion:
The possible values of
