Calculated 4023

How much does the glass of a display cabinet with dimensions of 3m x 2m and a thickness of 10mm weigh if the weight of the glass is calculated based on its specific volume weight, which is 2600 kg/m³? Therefore, the weight of one sheet of glass measuring 1 x 1 meter and 1 mm thick is 2.6 kg.

Correct answer:

x =  156 kg

Step-by-step explanation:

$$\begin{gathered} a=3\text{m} \\ b=2\text{m} \\ S=a\cdot b=3\cdot 2=6{\text{m}}^2 \\ \sigma =2.6{\text{kg/m}}^2\text{/mm} \\ h=10\text{mm} \\ x=S\cdot h\cdot \sigma =6\cdot 10\cdot 2.6=156\text{kg} \end{gathered}$$
