Answer 2

Answer

wall Measurements

length- 8m

breadth- 4m

height- 22.5cm= 0.225m

volume of the wall = length X breadth X Height

                              = 8x4x0.225m

                              = 7.2m^2

measurement of bricks

length =25cm =0.25m

breadth=12.5cm= 0.125m

height= 8cm=0.08m

volume of one brick= length X breadth x Height

                                  =0.25x0.125x0.08m^2

                                  =0.0025m^2

no. of bricks required to make the wall=

                                                       = volume of the wall÷ volume of the brick

                                                       =7.2÷0.0025

                                                        =2880
