Bricks                                    Wall

l=25 cm                                l=6 m =600 cm

b=12.5 cm                            b=50 cm

h=7.5 cm                              h=5 m =500 cm

volume of wall=l x b x h

                       =600 x 50 x 500

                       =15000000 cubic cm

volume of mixture =1/20 x 15000000

                              =750000 cubic cm

volume left =15000000 - 750000

                   =14250000 cubic cm

required brick =14250000/25 x 12.5 x 7.5

                        =6080 bricks
