Question

An object has a mass of 48 g and it has a height of 5 cm a width of 2 cm and a length of 5 cm. what is the density of the object?

Answer 1

Answer:
`0.96 g/cm^(3)`

Step-by-step explanation:

Density
`\rho` is defined as the relation between the mass
`m` of an object and its volume
`V`:

`\rho=(m)/(V)` (1)

On the other hand, the volume of the object (assuming it has a rectangular shape) is:

`V=(length)(height)(width)` (2)

Where:

`length=5 cm`

`height=5 cm`

`width=2 cm`

Then:
`V=(5 cm)(2 cm)(5 cm)=50cm^(3)` (3)

Substituting (3) in (1) and taking into account
`m=48 g`:

`\rho=(48g)/(50 cm^(3))` (4)

`\rho=0.96g/cm^(3)}` (5)
