Question

A cubical object of side 15 CM weight 1.35 kg calculate density in KG / metre cube

Answer 1

Explanation:

Given :-

Mass (m) = 1.35 kg

Side (a) = 15 cm = 0.15 m

To Find :-

Density = ?

Calculation :-

We know that,

Volume of a Cube = a x a x a = {a}^{3}a

3

= 0.003375 {m}^{3}0.003375m

3

Density = Mass / Volume

=> ρ = 1.35 / 0.003375

=> ρ = 400 kg/m^3.

Therefore, density in kilogram per cubic metre is 400 kg/m^3.

Formulas Used :-

Volume of a Cube = a x a x a = {a}^{3}a

3

= 0.003375 {m}^{3}0.003375m

3

Density = Mass / Volume

What is Density ?

Density is the physical property of matter.

Mass per unit volume is known as density.

Density is also known as volumetric mass density.

Density is represented by ρ.

Answer 2

Explanation:

density=mass/volume

density= 0.15/1.35

density =9 kg/m3
