Intext problem 1.5
Exercise condition:
5
m.
A box is made up of iron and it has a volume of
125
\(cm^3\).
Find its mass
.
Density of iron is
7.8
\(g/cm^3\).
[
NOTE
: Enter the answer up to two decimal places.]
\(D =\)
7.8
\(g/cm^3\)
\(V =\)
125
\(cm^3\)
The formula for density is
\(\text{Density} = \frac {\text{Volume}} {\text{Mass}}\)
\(\text{Density} = \frac {\text{Mass}} {\text{Volume}}\)
\(\text{Density} = \frac {\text{Mass}} {\text{Area}}\)
