Question

Density An object has a mass of 80 g. It is 3 cm wide, 4 cm tall and 2 cm long. What is the density of the object?​

Answer 1

the density of the object is 3.33
`\,(g)/(cm^3)`

Step-by-step explanation:

Use the formula for density:

`density=(M)/(V)`

where M is the mass of the object, and V its volume.

In our example, we have:

Volume V = 3 x 4 x 2 cubic cm = 24 cubic cm

Then the density is:

`density=(M)/(V)=(80)/(24) \,(g)/(cm^3) =3.33 \,(g)/(cm^3)`
