Question

Answer the following numerical on density:

1. Convert 13.6 g/cm^3 to kg/m^3.

2. Convert 4200 kg/m^3 to g/cm^3.

3. The volume of an object is 8 m^3 and its mass is 84 kg. What is the density of the object?

4. The volume of a block is 5 m^3. If the density of the block is 250 kg/m^3, what is the mass of the block?

Plz, answer it fastly. I will mark the first answer, if fully correct, as the Brainliest.

Answer 1

Answer:

1 g/cm^3 = 10^3 kg/m^3,

1 kg/m^3 = 10^-3 g/cm^3

density = mass/volume

1) 13.6 g/cm^3 = 13.6 × 10^3 kg/m^3 = 13600 kg/m^3

2) 4200 kg/m^3 = 4200×10^-3 g/cm^3 = 4.2 g/cm^3

3) density = mass/volume

= 84/8

= 10.5 kg/m^3

4) density = mass/volume

so, mass = density × volume

= 250×5

= 1250 kg
