How many lines did Bill draw for the squares? ** For the squares, he drew 32 lines because 8 times 4 equals <<8*4=32>>32.
How many lines did Bill draw for the pentagons? ** For the pentagons, he drew 20 lines because 4 times 5 equals <<4*5=20>>20.
How many lines did Bill draw in total? ** He drew 88 lines in total because 36 plus 32 plus 20 equals <<36+32+20=88>>88.
