    A pound of bricks
    Alexy Pagan
    For those that normally live their life, a pound is a pound. Even for those like me that study physics and engineering, a pound is a pound. Even knowing this, books and history says that a pound of gold and precious stones are measured in troy pounds (1 troy pound = 12 ounces)and other things in avoirdupois pounds (1 avoirdupois pound = 16 ounces) meaning that a pound of gold weight less than a pound of brick.

    let us revise the question to use tons as the unit of weight measure.
    in reality, the space taken up by the feathers would also include a large amount of air (which has a lot of mass and therefore weight if you get enough of it), where bricks would be stacked together with little air between. The feathers would then weigh more when actually measured, but only because you aren't measuring just the feathers.

    ANS2:
    The ton is a mass unit--it measures how much "stuff" you have. Heaviness, how hard gravity pulls a mass to another object, is measured by weight units. The avoirdupois system uses the pound as a unit of mass. There are 2000 pounds in an avoirdupois ton. Weight is measured in slugs.

    Since a ton of feathers has the same mass as a ton of bricks we are left to determine which has a greater attraction to the earth (weight). Two factors determine this measurement: "How far is the center of gravity from the center of the earth?" and "Are there any countering forces?"

    In a pile of bricks, the center of gravity is slightly closer to the center of the earth than would be the center of gravity of a pile of feathers. The gravitational attraction on the bricks would be greater than on the feathers.

    Feathers occupy more space than bricks of the same mass and, therefore displace more air. Air would provide a buoyant force countering the force towards the center of the earth.

    For these two reasons, a ton of bricks weighs slightly more than a ton of feathers

    well, the original trick question is whether a pound of gold or a pound of feathers weigh more. and it being a "trick" question could certainly be taken apart as any witticism losing the humor in technicalities.

    Let's borrow a rather eloquent explanation:

    A pound of feathers is measured in avoirdupois weight, in which one pound equals 16 ounces. Precious metals are measured in troy weight, in which one pound equals 12 ounces. However, the ounces are not measured in the same way. In avoirdupois weight, one ounce = 437.5 grains. In troy weight, one ounce = 480 grains. So, one pound of feathers weighs (16)x(437.5 grains) = 7,000 grains. One pound of gold weighs (12)x(480 grains) = 5,760 grains. Therefore, an ounce of gold weighs more than an ounce of feathers (480 grains to 437.5 grains), but a pound of feathers weighs more than a pound of gold (7,000 grains to 5,760 grains).



    like asking "Do they have a fourth of July in England?" which, of course, they do, but the object is to cause one to consider whether they CELEBRATE the fourth of July in England (which, of course, they don't) resulting in many people (americans) answering "No they don't" which leaves you able to ask "oh, so they go right from the 3rd to the 5th?" and get a chuckle that you were successful in tricking the mind.

    thus humor!

    So, intellectuals, debate away. It's still funny.

    Please read this very carefully. I'm going to show you how to solve this little equation. And just for the hell of it, I'm going to set the bricks and feathers to varibles.

    1lbs = 1lbs
    You following me so far?

    Bricks = a
    Feathers = b
    Got that?

    a = 1lbs
    b = 1lbs
    Remember this.

    Then A = B

    So 1 pound of Bricks = 1 Pound of Feathers
    Thank you.

    but the bricks are much more dense so there will be a large ratio of feathers to bricks even though they weigh the same

    But I believe one single brick is more than at least about 4 lbs. And you made bricks plural. =P Unless you're talking about miniature bricks. But those would be weird to see. lmao
