Question

the lemght breadth and height of a metal block of mass 160 are 50cm 40cm and 20cm respectively. calculate the density of the metal block

Answer 1

Answer:

solution,

length(l)=50 cm

breadth(b)=40 cm

height(h)=20 cm

mass(m)=160 kg

volume(v)=?

Density of metal block(d)=?

we know that,

V=l*b*h

=50*40*20

=40000cm^3

=40000/1000000m^3

=0.04m^3

Again,

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

$= \frac{160}{0.04}$

$= 4000$
