A rod shaped bacteria has a diameter of 0.6µm and length of 3&mi...

Volume of rod shaped cell = πr²h
r = Radius = 0.3μm or 0.3 x 10^-6 m
h = Length = 3μm or 3 x 10^-6 m
Volume of cell =πr²h
= 3.14 x (0.3 x l0^-6)² x 3 x 10^-6 m³
= 0.84 x l0^-18 m³
Given density = 1.5 x 10³ g L
Since Im³ = 1000 litres
Density = 1.5 x 10⁶g 1000L or 1.5 x 10⁶g/m³
Mass = Volume x Density
= 0.84 x I0^-18x 1.5 x 10⁶
= 1.26 x 10^-12 g
