Homework Help Overview

The discussion revolves around determining the volume of an object needed to displace 2 gallons of water, along with exploring the dimensions required for such an object. The subject area pertains to fluid mechanics and volume displacement.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Participants explore the relationship between volume and displacement, questioning the assumptions in the original problem statement. There is a focus on the implications of density and shape on the dimensions of the object.

Discussion Status

The discussion is active, with participants offering differing perspectives on the validity of the question and its assumptions. Some guidance has been provided regarding the conversion of gallons to cubic meters, but there is no consensus on how to approach the problem due to its perceived flaws.

Contextual Notes

Participants note that the question lacks clarity regarding the density and structure of the object, which complicates the determination of dimensions. There is an underlying concern about the appropriateness of the question for a physics context.

Homework Statement



If you wanted to displace 2 gallons of water, what would the volume of the object need to be?

From there, what would the dimensions of an item need to be to match the required volume?

Homework Equations





The Attempt at a Solution

 
Physics news on Phys.org
The question itself leaves much to think about as the displacement of water requires something of equal weight, not of equal volume. Therefore, the question itself has some fundamental flaws.
 
the answer is 2 gallons
 
Yes the "gallon" is a unit of volume. The dimensions of the object would depend on the shape of your object. If you really can't figure this one out yourself maybe you should reconsider going into the field of physics. 2 gallons is equivalent to 0.007570 cubic meters. From there it should not be very difficult to get your dimensions.
 
That is not exactly correct stongio. The question, as I've said, has some fundamental flaws. The question asks for the dimensions of "an item" of unknown density and structure. As such, it cannot really be solved. The answer '2 gallons' simply does not do the question justice.
