    Number of bricks is 5

    Step-by-step explanation:

    We have volume of wall 60m^3. Then we are also given number of bricks size 20cm * 12cm * 5cm.

    By multiplying this number we grt 1200cm^3. But answer is needed in meter so divide 1200 with 100 because to change cm into m we need to divide with hundred. Then we have 12m^3 as volume of bricks.

    To get no. of bricks we have formula

    N = volume of wall : volume of bricks

    N = 60 : 12

    N = 5

    Thus the number of bricks is 5.

    Ask me again if you got confused i will explain it more briefly ...
