Volume of brick = l * b* h

                            = 20 * 12 * 8

                           =1920 cm³

1 m = 100 cm      16.8m = 168 * 100 cm

2.5 m = 2.5 * 100 cm  

Volume of wall = 16.8 *100 * 2.5*100 * 12

                         = 5040000 cm ³

No. of bricks required to construct the wall = 5040000/1920

                                                                        = 2625 bricks

Answer:

Volume of brick = l * b* h

                           = 20 * 12 * 8

                          =1920 cm³

1 m = 100 cm      16.8m = 168 * 100 cm

2.5 m = 2.5 * 100 cm  

Volume of wall = 16.8 *100 * 2.5*100 * 12

                        = 5040000 cm ³

No. of bricks required to construct the wall = 5040000/1920

                                                                       = 2625 bricks
