Question

3. Find the density of an object
whose mass is 80 gram and volume is 4m³​

Answer 1

Answer:

Density = mass/volume

80g = 80/1000 kg = 0.08kg

So, density = 0.08/4

= 0.02kg/m³

Hope This helps ☺️

Answer 2

ANSWER:

Given:

• Mass = 80g
• Volume = 4m³

To Find:

• Density of the object

Solution:

We know that,

⇒ Density = Mass/Volume

So,

⇒ Density = 80g/4m³

We know that,

⇒ 1g = 0.001kg

So,

⇒ 80g = 80 × 0.001kg = 0.08kg

Therefore,

⇒ Density = 0.08kg/4m³

⇒ Density = 0.02 kg/m³

Hence, density of the object is 0.02 kg/m³.

Formula Used:

• Density = Mass/Volume

Definitions:

• Density: It is defined as mass per unit volume. It's SI unit is kg/m³.
• Mass: Amount of matter in a substance. It's SI unit is kg.
• Volume: Amount of space a substance occupies. It's SI unit is m³.
