Determine the mass of glass pane 60 cm long, 50 cm wide and 0.5 cm thick? How do you find the density of this glass?

Glass volume V:
V = 0.6 m * 0.5 m * 0.005 m = 0.0015 m³.
According to the reference book, we find the density of the window glass r:
r = 2500 kg / m³.
m = rV = 2500 kg / m³ * 0.0015 m³ = 3.75 kg.
If there is no reference book, then the size of the glass can be used to find the volume V, and by weighing the mass m. Formula for calculating density:
r = m / V.
Answer: m = 3.75 kg.
