By \"similar\" you really mean, \"congruent\", so same size and shape.\r

\n" ); document.write( "\n" ); document.write( "The rate for 1 worker in the first described group is 1 \"paint the building\" in $\"20%2A8=160\"$ days.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "For a group of n workers, the work rate of this group is $\"n%281%2F160%29\"$ jobs per day. The basic idea of uniform rates for task completion or doing a job is R*t=j for Rate, time, job. Your question simply becomes $\"highlight%28highlight%28%28n%2F160%2915=1%29%29\"$ , using units of days and job. n is the count of the workers needed in the group, and unknown which easily is solvable. \n" ); document.write( "
