The volume of a normal person, what is the approximate volume of a person

The volume of a normal adult: when the human body sinks or floats in the water, the density of the person is equivalent to the density of water, when the specific gravity of water is 1, the density is 1000kg cubic meters, and then divide the mass by the density to get cubic meters.

So the normal volume of a person is around the cubic meter.

The volume of a normal adult (59kg): a person is sinking or floating in water, so the density is roughly the density of water. The specific gravity of water is 1, and the density is 1000kg cubic meters. Divide the mass by the density, and the volume is cubic meters.

The volume of a person is approximately divided by 1000 by body weight, such as the volume of a person of 50kg is about cubic meters.

The density of a person is approximately equal to the density of water, that is, 1 10 to the 3rd power of kilograms per cubic meter, assuming that the mass of a person is 50kg According to the formula: m divided by v, it can be seen that the volume of a person cubic meter cubic meter = 50 cubic decimeters, so the volume of a person is about 70 cubic decimeters (because the density and mass of a person are approximated, there is a deviation).

Unit conversion of volume:

cubic decimeter = 1000 cubic centimeters = 1000000 cubic millimeters = 1 liter = 1000 milliliters = cubic inches.

Cubic centimeter = 1000 cubic millimeter = 1 milliliter = cubic inch.

cubic meters = 1000 cubic decimeters = 1000000 cubic centimeters = 1000000000 cubic millimeters = cubic feet = cubic yards.

Difference Between Area and Volume:

1. Overview of area and volume of different volumes.

Volume: When the space occupied by an object is three-dimensional, the size of the space it occupies is called the volume of the object.

Area: When the space occupied by an object is two-dimensional, the size of the space it occupies is called the area of the object.

2. The calculation method is different.

Area: The formula for calculating the cuboid is (kx width + length x height + width x height) x2, and the area formula for the cube is edge length x floor length x6.

Volume: The volume of a cuboid is calculated as length x width x height, and the volume of a cube is calculated as edge length x edge length x edge length.

3. The unit of measurement is different.

The unit of volume is the cube: the unit of volume is used, the unit of area is squared, and the unit of area is used.

The volume of a normal adult is about cubic meters. When the human body sinks or floats in the water, the density of the person is equivalent to the density of water, when the specific gravity of the water is 1, the density is 1000kg cubic meters, and then divide the mass by the density to get cubic meters. So the normal volume of a person is around the cubic meter.

Also using the method that Archimedes came up with, fill a bathtub with water, enter the bathtub and submerge the whole body into the water, and accurately measure the water added to the bathtub until it is full. The volume of water added a second time is your volume.

Application of density

1. Determine whether the object is solid or hollow.

There are generally three ways to determine whether an object is hollow or solid:

1) According to the formula, find its density, and then compare it with the density of the substance, if < is hollow, if = , it is solid.

2) Knowing the mass, from the formula, find v, and then compare with v, if v, then it is hollow, if v=v, then the object is solid.

3) Treat the object as a solid object, use it, find the mass of a solid object with a volume of v, and then compare m with the actual mass of the object m, if m > m, then the object is hollow, if m=m, then the object is solid.

2. Calculate the internal pressure and buoyancy of the liquid. (Density can also be used to calculate the cylinder pressure).

The mass of the person (in kilograms) is divided by the density of the person (i.e. divided by 1000).

Find a tank full of water. People go in. How much water is overflowing. Just calculate the volume of water.

The normal volume of a person is around the stool rotten. The density of the human body is g cm, and the adult volume can be calculated by applying the formula of volume = mass density. Generally, the mass of adults is between 40kg-80kg, and the density of the human jujube-type leakage divided by the rent is 1020kg m, and the volume can be estimated to be about m by rounding.

When the human body sinks or floats in the water, the density of the person is equivalent to the density of the water, and the volume of a normal person can be obtained by dividing the mass by the density.

Density is one of the properties of matter, generally different substances have different densities, density can be used to calculate volume, can also be used to identify substances.

The normal volume of a person is around m. The density of the human body is g cm, and the adult volume can be calculated by applying the formula of volume = mass density. The average adult mass is between 40kg-80kg, divided by the density of the human body 1020kg m, and the volume can be estimated to be about m.

When the human body sinks or floats in the clear water, the density of the person is equivalent to the density of the water.

Density is one of the pre-Tessen properties of matter, generally different substances have different densities, density can be used to calculate volume, but also can be used to identify substances.
