Depending on where you live: mass would be grams and kilograms in metric or ounces and pounds in US customary or imperial.
Volume could be liters, cubic centimeters, milliliters. Or fluid ounces, tablespoons, gallons, cubic inches, cubic feet.
Density can be: grams/milliliter, kilograms/liter, or pounds/cubic foot.
density is a measure of mass per unit volume, so any unit of mass (kg,lb,tonne) per volume (metres cubed, cubic feet) etc will work.
The two most common ones are
kg/m^3 (kilograms per metre cubed, popular in Europe)
and
lb/ft^3 (pounds per cubic foot, popular in the USA)
a fundamental unit is kg or m - (also seconds, amps, candela and moles). Density is kg/m3 and is thus derived.
Volume is the space occupied by an object or substance. When working with density, volume is important because density is defined as mass per unit volume. By knowing the volume of a substance and its mass, you can calculate its density.
The volume of the substance can be calculated using the formula: volume = mass/density. In this case, the volume would be 80/40 = 2 cubic units.
The unit of length in SI is metre (m). The unit of mass in SI is kilogram (kg). The unit of volume in SI is litre (L). The derived unit of density in SI is Mg/m3 (or g/cm3). Length, mass, density, volume are not units but characteristics of materials and objects.
To convert volume to mass, you need the density of the substance. Multiply the volume by the density to get the mass using the formula: mass = volume x density. The units of volume and density must be compatible for accurate conversion.
Unit of length is m and that of mass is kg Now volume is length x length x lenght. SO volume would have the unit mxmxm = m3 Density = mass / volume So unit for density = kg /m3
The units for the volume if you are measuring any liquid or solid is metre^3/cm^3 as density = mass/volume. The units for mass is grams
The metric units for: Length: meters Mass: grams Weight: newtons Volume: liters Density: grams per cubic centimeter (g/cmΒ³)
To convert density to mass, you need to know the volume as well. The formula to calculate mass from density and volume is mass = density x volume. Multiply the density of the substance by the volume in cubic units to get the mass in units of mass (e.g. grams, kilograms).
a fundamental unit is kg or m - (also seconds, amps, candela and moles). Density is kg/m3 and is thus derived.
Mass: kilogram, length: meter, volume: cubic meter, density: kilogram / cubic meter, temperature: celcius or kelvin.
The mass of a cube is determined by the density of the material it is made from, along with its volume. The equation to calculate mass is mass = density x volume. If you provide the density and volume of the cube, we can calculate the mass for you.
Density = Mass/Volume = 4.2 units of mass/2units of volume = 2.1 units of mass per unit of volume.
