Question 1137382

 a platform bed {{{7 }}}feet wide and {{{10}}} feet long, have an area of 

{{{7ft *10ft=70ft^2}}} 

if have {{{6 }}}inches wide by{{{ 2}}} feet long boards, area will be

 {{{6in*2ft }}}.......convert inches to feet: {{{1in=0.0833333ft}}}

{{{6*0.0833333ft*2ft =0.9999996ft^2}}}

now divide the area of the platform bed by the area of the board

{{{70ft^2/0.9999996ft^2=70/0.9999996=70.00002800001=70}}} 

so, you need {{{70}}} boards

if you already have one board, you need {{{69}}} more
