Answer: Total volume of fat in his body is [tex]0.015m^3[/tex]
Explanation:
Density is defined as the mass contained per unit volume.
[tex]Density=\frac{mass}{Volume}[/tex]
Given:
Density of fat cells = [tex]900kgm^{-3}[/tex]
mass of fat cells = 20% of the mass of a 70 kg student's body is fat= [tex]\frac{20}{100}\times 70=14kg[/tex]
Volume of fat = ?
Putting in the values we get:
[tex]900kgm^{-3}=\frac{14kg}{volume}[/tex]
[tex]Volume=0.015m^3[/tex]
Thus total volume of fat in his body is [tex]0.015m^3[/tex]
