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
