Question

2. A block has a mass of 36.0 grams. It has a height of 2.0 cm, a length of 3.0 cm, and a

width of 3.0 cm. What is the density of the block?

Answer 1

2g/cm^3

Step-by-step explanation:

This Question tests on the concept of Density.

Density

Density, as the name goes, its how dense the object is. It is also defined as mass per unit volume. It has the units:

g/cm^3 or kg/m^3.

Formula to find Density =

`(mass)/(volume)`

Application:

Since the parameters of this quesion are given in grams and cm, we will leave the density as g/cm^3.

We know that the mass of the block = 36grams

and the volume of the block = Product of Length , Height and Width = 2 cm × 3 cm × 3 cm =

`18 {cm}^(3)`

Now we can find the density of the block:

Density of object =

`(36)/(18) \\ = 2g \: per \: {cm}^(3)`

Therefore the density of this block = 2g/cm^3.
