Figure on top is 8 times 9 (to find volume)
the figure on top has a volume of 72 cm<span>^3
the volume of the lower figure:
3 times 9 times 5 = 135 cm</span><span>^3
72+135=207 cm</span><span>^3
the volume of both figures is 207 cm</span><span>^3</span>
        
                    
             
        
        
        
Kim = 135/9 = 15 miles per week
Eric = 102/6 = 17 miles per week
