Question

how many bricks measuring 18cm X 12cm X 10cm will be required to build a wall 12-meter -long ,6dm wide and 4.5 m high .Also find the cost of bricks at ₹225 per 100 bricks

Answer 1

number of bricks needed to build a wall a r e 15000 and the cost of bricks RS 33000

Answer 2

LSA of bricks = l×b×h
                      =18×12×10
                      =18×120
                      =2160m²

dimensions of the wall = 12m
                                        6dm=0.6m
                                       4.5m
∴LSA of wall=32.4m²
