Answer:

4320 bricks can fit into the wall.

Step-by-step explanation:

volume of wall=length * breadth * height

                        =15m * 1.8m *37.5cm

                        =1500cm*180cm*37.5cm             [1m=100cm]

                        =10125000cm^3

volume of 1 brick=length * breadth * height

                           =25cm *12.5cm *7.5cm

                           =2343.75cm^3

number of bricks which can accomodate in that wall,

volume of wall___

volume of 1 brick

so

10125000cm^3/2343.75

=4320
