Mass of a building problem.?

Question

if you knew the length (7ft), width(7ft), and highth(7ft) of a cubed building that weighs 500 pounds, could you find the mass? If so, how?

Answer 1

Mass and weight are directly related by the accelleration of gravity:  F=M*A where F = force (weight is a force), M = Mass and A = accelleration of gravity.  The size of the building has no effect on the Mass, only on the volume.

So, 500 pounds = M * 32.2 ft/sec^2

M = 500/32.2 = 15.53 slugs

Answer 2

If it is on earth, the mass in pounds equals the weight in pounds.

so 500 pounds is the answer.

.

Answer 3

The mass of anything that (on earth) weighs 500 pounds, is 227 kg.  The dimensions of the cube are irrelevant

In physics, weight is a force, and can be measured in either Newtons or pounds ("Newton" is the metric unit of force; "pound" is the imperial unit of force).  Neither one of them is the mass.  Mass is typically measured in grams or kilograms.

In physics, you get the mass by dividing the weight (i.e. the force of the pull of gravity) by the local gravitational acceleration.  If you do this on earth, the mass corresponding to 500 pounds is 227 kg.

Answer 4

If the weight of a body is given in pounds, then its mass is equal to

Pounds/Acceleration due to gravity.

In the English system, the acceleration due to gravity is equal to 32.3 ft/sec^2. Hence,

mass = 500/32.2 = 15.53 slugs

NOTE --- "slugs" is the unit of mass in the English system.

Answer 5

well you are confusing what weight is. weight is a force, so it is measured in newtons. what you have said is 500 pounds is actually the mass, not the weight.
