the area of {{{2830}}} pieces of wood measuring {{{3.5cm}}} by {{{14cm}}} is
{{{2830*(3.5cm*14cm )=2830*49cm^2=138670cm^2}}}

since you covering floor, convert that area into {{{m^2}}}

{{{1cm=0.01m}}}=>{{{1cm^2=0.0001m^2}}}

{{{138670*0.0001m^2=13.867m^2}}} or =  {{{13 m^2}}}{{{ 86 dm^2}}}{{{ 70 cm^2}}}
