l = 30cm = 0.3m \\ b =25cm  = 0.25m \\ h = 2cm = 0.02 m \\  \\ volume \: of \: the \: glass = l \times b \times h \\  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \: \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:   \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  =   0.3 \times 0.25 \times 0.02  \\  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \: = 0.00150  {m}^{3}  \\  \\ density \:  =  \frac{mass}{volume}  \\   \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  =  \frac{7.5}{0.0015}  \\  \:  \:  \:  \:  \:  \:   \:  \:  \:  \:  \:  \:  \:  \:  \:  \: \:  = 5000 \:  {kg \: m}^{ - 3}
