The answer two this question depends on two factors:
- Determining the volume of the shape in question.
- Determining the weight the of the matter the object is composed of.
For example a 3 dimensional square that is 1 meter in length, 1 meter in width and 1 meter in height is filled with water. To determine the weight of the water:
- The volume formula for a rectangle is volume = length X width x height; In our case volume = 1 x 1 x 1 = 1 m^3 (one meter cubed)
- the wight of water is 1 per cubic meter.
Therefore 1 m^3 of water weighs 1 kg.
Density is defined as the mass divided by the volume. This definition can, in many cases, also be used to measure the density.
formula
Its grams
pythagoras
THAT IS THE FORMULA! Just solve that! Formulas are only needed to calculate certain measurements or numerals in algebraic equations used to determine things like a radius, or diameter of a circle.
weight=mass*gravity
You can't actually calculate it, which is the main reason why, in placeswhere they need to know the weight of things, you find scales.If you happen to know the object's mass, you can multiply that by the localacceleration of gravity, and the result is the object's weight. But what arethe chances of that happening !
density=mass/volume
Mass divided by volume
One formula that is often used is: distance = speed x time
The formula for calculating weight of a solid shaft is dia x dia x length x 7.8 x 1000000. This formula is the most commonly used.
Relative gravitational potential energy.
Mass of a body and its speed are needed to calculate kinetic energy. Kinetic energy of an object = mv2/2 This formula is useful only when object's speed is much less than speed of light.
It is equal to 1/2 MV2, M=mass, V=velocity
Mass is a property of matter and is therefore a constant. Weight however can change, it is the force exerted by that mass in a gravity field. Thus in different gravity fields a constant mass will weigh differently. Weight = Mass * the acceleration of gravity.
Mass is the measure of an object's inertia, which is a body's tendency to resist acceleration. Ben-jammin's answer: mass is the amount of matter an object has. it's used to calculate weight with the formula (mass)x(gravity) = weight.
the formula used to calculate a slope is: m=y2-y1/x2-x1
