The glass

1 m³ of glass weighs 2600 kg. Calculate the weight of the glass glazing panel with dimensions of 2.5 m and 3.8 m if the thickness of the glass is 0.8 cm.

Correct answer:

m =  197.6 kg

Step-by-step explanation:

$$\begin{gathered} \rho =2600{\text{kg/m}}^3 \\ a=2.5\text{m} \\ b=3.8\text{m} \\ c=0.8\text{cm}\to \text{m}=0.8:100\text{m}=0.008\text{m} \\ V=a\cdot b\cdot c=2.5\cdot 3.8\cdot 0.008=\frac{19}{250}=0.076{\text{m}}^3 \\ m=\rho \cdot V=2600\cdot 0.076=197.6\text{kg} \end{gathered}$$
