An object of area 15 cm and height 2 cm has a mass of 50 x What is its density in SI system Ans. 1667 kg/m)

Answer 2

Answer:

• 1600 km/m³

Explanation:

Given : An object of area is 15 cm² and height 2 cm has the mass of 50g.

To find : What is it's density in SI unit.

Using formula :

→ $\sf{Density = \dfrac{Mass}{Voulme}}$

→ $\sf{Volume = Area \times height}$

Calculations :

→ $\sf{15 \times 2 = 30 cm{}^{3}}$

→ $\bf{50 \: g}$

Now, using the above values :

→ $\sf{Density = \dfrac{50}{30}}$

→ $\sf{Density = \dfrac{5}{3}}$

→ $\bf{Density = 1.6 gm/cm{}^{3}}$

Converting it into S1 units :

→ $\sf{SI = 1.6 \times 1000 \: kg/m{}^{3}}$

→ ${\bf{\boxed{\sf{SI = 1600 \: kg/m^{3}}}}}$

Therefore, 1600 km/m³ is the density in SI units.
