Question

The length breadth and height of a metal block of mass 160 kg are 50 cm, 40 cm and 29 cm
respectively Calculate the density of the metal block​

Answer 1

Answer:

50 × 40 × 29

= 58,000

= 58,000 - 160

57,840

Answer 2

Given that :-

mass = 160 kg

length = 50 cm

breath = 40 cm

height = 29 cm

to find :-

density

As we know that,

density  = mass/volume

Si unit is Kg/m³

but we have length , breath and height in cm

Solution :-

firstly find volume and convert into m³

Now,

volume = length × breath × height

           = 50 × 40 × 29 $cm^3$

            = 58000 $cm^3$

convert into $m^3$

$0.058 m^3$

Since,

density = $\frac{mass}{volume}$

           = $\frac{160}{0.058}$

           = 2758.620 Kg/m³

Answer :-  2758.620 Kg/m³
