Answer 1

Step-by-step explanation:

Answer

Length of brick=25cm

breadth of brick =15cm

height of brick=10cm

volume of brick =length×breadth×height

=25cm×15cm×10cm

=3750cm3

length of wall=6m=600cm

breadth of wall=0.5m=50cm

height of wall =2.5m=250cm

volume of wall=length×breadth×height

=600×250×50=7500000cm3

the number of bricks required=37507500000

=375750000

=2000

hence, number of bricks =2000
