Density
76
mass / volume = 48g / 6cm3 = 8 g/cm3
To find the density of an object, it would be D=m/v.So the density would be: 7.3099415204678362573099415204678 kg/L.But in this, there are also significant figures, and so in 6.25, there are 3. Therefore, the answer cannot be more precise than the given equation.So it would round to 7.30.Density = 7.30 kg/L.

The volume is 8 cubic centimetres.
The density of a material is defined as its mass per unit volume, density = m/v (mass/volume) One unit for this is grams/cm3. The weight is 12 g, and the volume is: v = 3 cm x 2 cm x 1 cm = 6 cm3 plugging in: density = m/v = 12 g/6cm3 = 2 g/cm3
Density = mass/volumeFor the cube of water having a mass of 1g:Volume of a cube of water measuring 1cm X 1cm X 1cm =1cm3.Density = 1g/1cm3 = 1g/cm3For the block of "plasting" having a mass of 4g:Volume of the block of plasting measuring 2cm X 3cm X 1cm = 6cm3.Density = 4g/6cm3 = 0.7g/cm3I will let you decide which has the greatest density.
The units of the question are incorrect. It's like asking "What is the fuel economy of a car if it travels 1722398016 on a pint and a half of petrol?" 1722398016 what? Miles? Angstrom units? It's far more important to understand units than to be able to work a calculator!
