    Kevin will take 3 hours to make all pieces.

    Step-by-step explanation:

    Kevin is building a large model of a soccer ball which is made of 20 hexagons and 12 pentagons.

    Time taken by Kevin to measure and cut each hexagon = 6 minutes

    Therefore, time taken to make 20 hexagons = 6*20 = 120 minutes

    Similarly time taken by him to measure and cut a pentagon = 5 minutes

    So, time taken to make 12 pentagons = 12*5 = 60 minutes

    Total time taken to measure and cut 12 pentagons and 20 hexagons = 60+120 = 180 minutes

    Therefore, Kevin will take 180 minutes or 3 hours to make all pieces.
