Maximum Volume of an Open Top Box

It's just something I'm interested in.In summary, the conversation discusses a question about finding the volume of a rectangular prism using the given equations and the height, x. The conversation also includes a discussion about alternative methods of solving the problem without using the derivative or graphing.

Homework Statement


Is there another way to do this question?
Is this right?

L = 50-2x
W = 40-2x
Height= X

Homework Equations



//

V=L x W x H
V= (50-2x)(40-2x)(x)
V= (2000 -180x +4x²)(x)
V= 2000x -180x² +4x³
V= 4x³ - 180x² +2000x
V' = 12x² -360x +2000
X = (360 (+/-)sqrt(360²-4(12)(2000))) / 2(12)
X = 7.36...

How would I do this without using f ' ( x ) ? nor graph it

Are they asking you to do it without taking the derivative and setting it equal to zero?
Graphing is never necessary. Just for convenience.

No, but how would I do that?

It's not required or anything nor is it asked.
 

Related to Maximum Volume of an Open Top Box

What is the formula for finding the maximum volume of an open top box?

The formula for finding the maximum volume of an open top box is V = l * w * h, where l is the length, w is the width, and h is the height of the box.

How do I determine the dimensions of the open top box for maximum volume?

To determine the dimensions of the open top box for maximum volume, you can use the formula V = l * w * h and plug in different values for l, w, and h until you find the combination that gives the highest volume. Alternatively, you can use calculus to find the critical points of the function V = l * w * h and determine which combination of dimensions gives the maximum value.

What is the difference between maximum volume and optimal volume?

Maximum volume refers to the largest possible volume that can be achieved for a given open top box, while optimal volume refers to the volume that would be most desirable or beneficial in a specific situation. For example, the maximum volume of a container may be larger than the optimal volume for shipping purposes.

Are there any limitations to the maximum volume of an open top box?

Yes, there are limitations to the maximum volume of an open top box. The dimensions of the box must be physically possible and cannot exceed the size of the material being used to construct it. Additionally, the box must still be able to function as a container, meaning it must have a bottom and sides to hold the contents.

Can the maximum volume of an open top box be achieved with any shape?

No, the maximum volume of an open top box can only be achieved with certain shapes, such as a rectangular prism or a cube. Other shapes, such as a sphere or pyramid, cannot achieve the maximum volume because they do not have a flat top to create an open top box.
