Glass pendant weight

Calculate the weight of the pendant - a regular four-side prism made of glass. The density of the glass is 2.5 g / cm³, the edge of the base is 2 cm, and the height of the pendant is 5.5 cm.

Final Answer:

m =  55 g

Step-by-step explanation:

$$\begin{gathered} \rho =2.5{\text{g/cm}}^3 \\ a=2\text{cm} \\ c=5.5\text{cm} \\ V=a^2\cdot c=2^2\cdot 5.5=22{\text{cm}}^3 \\ m=\rho \cdot V=2.5\cdot 22=55\text{g} \end{gathered}$$
