What is the density of a block of wood has a mass of 4g and occupies a volume of 5cm3?

Answer 1

Density is calculated by dividing the mass of an object by its volume. In this case, the density of the block of wood would be 4g divided by 5cm^3, which equals 0.8 g/cm^3. This means that for every cubic centimeter of the wood, there is 0.8 grams of mass.

Answer 2

The density of the block of wood is 0.8 g/cm3, calculated by dividing the mass (4g) by the volume (5cm3). Density is a measure of how much mass is contained in a given volume, so in this case, the block of wood has 0.8 grams of mass in every cubic centimeter of volume it occupies.

Answer 3

Density means mass per unit volume. Hence, mass of a body divided by it's volume will give us it's density.

Here mass = 4g, volume= 5cm3

So, density = mass/volume

=4g/5cm3

=0.8g/cm3

This is the average density of the wooden block. The density of block whole throughout it's body may not always be equal to this value. Some portions of block can be more dense and some less dense. But the average density of any body having mass= 4g and volume = 5cm3 is always 0.8g/cm3 .

Answer 4

The weight of a block is equal to 0.53 time V for volume times g. The weight of the oil displaced is equal to n V time 0.8 times g. The answer is 0.8 g/cm3.
