 \sf{height \:  =  \: 8cm} \\  \\  \sf{radius \:  =  \: 2cm } \: \\  \\    \mathcal{so \:volume \:of \: cylindrical \: camdle \:  would \: be : } \\  \\ \boxed {\pink{ volume = \pi \:  \times  \:  {r}^{2}  \times h}} \\  \\

 \bold{volume = 3.14 \times 8 \times 2} \\ \\   \bold{volume = 3.14 \times 16} \\  \\ \bold{volume = 50.40 {cm}^{3} }

Solving @ of 1cubic cm = 2.5 grams

 \mathcal{if \: 1 \: cm {}^{3}  \:  =  \: 2.5 \: grams \: } \\  \\  \mathcal{then} \\ \\   \mathcal{50.40 {cm}^{3} \: will \: be \: equal \: to \: x } \\  \\  \star \:  \bold{using \: direct \: propotion \:we \: get :  } \\  \\  \mathcal{weight \: of \: 50.40 {cm}^{3} of \: wax = 2.5 \times 50.40}

 \mathcal{weight \: of \: 50.40 {cm}^{3}  =126 \: gram } \\ \\  \\   { \boxed{\bold {\purple{answer = 126 \: gram}}}}
