Math Problem Statement
please calculate
Solution
The critical points found are and . However, the maximum volume calculation results in zero when using . This suggests that there may have been an issue with the substitution or calculation.
Let's manually re-evaluate the volume using the valid critical point :
Volume Formula:
Substituting :
I'll re-calculate this to ensure the correct maximum volume.The maximum volume of the box, when inches, is approximately 37.93 cubic inches.
This value corresponds to the dimensions:
- Length and Width of the base: inches (approximately 6.67 inches)
- Height: inches
