Answer:
Density of metal = 0.13 g/ cm³
Explanation:
Given data:
Width of metal sheet = 2 mm = 2/10 = 0.2 cm
Length of metal sheet = 15 cm
Height of metal sheet = 10 cm
Mass of sheet = 4 g
Density of metal = ?
Solution:
Density:
Density is equal to the mass of substance divided by its volume.
The symbol used for density is called rho. It is represented by ρ. However letter D can also be used to represent the density.
Units:
SI unit of density is Kg/m3.
Other units are given below,
g/cm3, g/mL , kg/L
Formula:
d =m/v
Volume = width× height × length
Volume = 0.2 cm× 10 cm× 15 cm
Volume = 30 cm³
d = 4 g/ 30 cm³
d = 0.13 g/ cm³
