Question

The weight of a ball is 2.125 kg and volume 280 cc. Calculate the density of the material?

Answer 1

Answer:

758.92 kg/$m^{3}$

Step-by-step explanation:

M = 2.125 kg = 17/8 kg

V = 280 cc

  = 280 *10^-6

Density (D) = M/V

D= 17/8 * 10^6/280

D = 758.92 Kg/$m^{3}$

Answer 2

The density of the material is $758.92\ \frac{kg}{m^{3} }$.

Step-by-step explanation:

Given:

The weight of a ball is 2.125 kg and volume 280 cc.

To Find:

The density of the material.

Formula Used:

$Density =\frac{Weight}{Volume}$   ---------------- formula no.01.

Solution:

As given - the weight of a ball is 2.125 kg and volume 280 cc.

Weight=2.215 kg

Volume $=280\ cm^{3}$

              $=280\times\frac{1}{10^{-6} }=280\times 10^{-6} \ m^{3}$

Applying the formula no. 01.

$Density =\frac{2.125}{280\times 10^{-6} }$

               $=\frac{2.125\times 10^{6} }{280}$

                $=758.92\ \frac{kg}{m^{3} }$

Thus,the density of the material is $758.92\ \frac{kg}{m^{3} }$.
