Answer
Density = 2.57 g/cm³ [ CGS ]
Density = 2570 kg/m³ [ MKS ]
Given
A piece of aluminum has dimensions 3 cm*4 cm*5.5 cm . Mass of the Aluminium is 170 g
To Find
Density
1 . CGS units
2 . MKS units
Points to be noted
MKS system :
It is a system of units in physical system of measurement that uses meter , kilogram and second as basic units
CGS system :
It's full form is Centimeter-Gram-second system where fundamental units are Centimeter , gram and second.
Density :
It is defined as mass acting per unit volume
MKS unit's of Density is Kg/m³
CGS unit's of Density is g/cm³
Solution
Volume = 66 cm³
Mass = 170 g
Density = ?
Apply formula ,
Since , 1 kg = 1000 g
and 1 m = 100 cm
