-- Measure its mass and volume.
-- Divide (mass) by (volume).
-- The answer is its density.
Density is mass divided by volume.
Density= mass/volume
by dividing the population of the country to the square density so divide both of them and you get the population density!!
To calculate density with only length, width, and height, you need to also know the mass of the object. Density is calculated by dividing the mass of an object by its volume, which can be found by multiplying length, width, and height. The formula for density is: density = mass / (length x width x height).
The density of a liquid affects the buoyancy of an object by determining whether the object will float or sink in that liquid. If the density of an object is greater than the density of the liquid, the object will sink. If the density of the object is less than the density of the liquid, the object will float.
An object will float in a fluid if its density is less than the fluid's density. If the object's density is greater than the fluid's density, the object will sink. If the object's density is equal to the fluid's density, it will be suspended at a specific depth.
To predict the density of a floating object, you can compare the density of the object to the density of the fluid it is floating in. For an object to float, its density must be less than the density of the fluid. You can calculate the density of the object by dividing its mass by its volume.
divide its mass by its volume
Use one of these equations when you know the mass & volume of a substance and you want to compute the density or volume of the object: v = m / d d = m / v When: d = density m = mass v = volume (the amount of space occupied or the holding capacity of something)
If an object has less density than water (or whatever liquid you are considering), it will float. And if it has more density then the liguid you are considering it will sinq
density of the object < density of the fluid
To compute mass using density and volume in liters, you use the formula: mass = density x volume. First, convert the volume from liters to cubic meters (1 liter = 0.001 cubic meters). Then multiply the density by the volume in cubic meters to find the mass.
