Answer 1

(l) length of wall =13.5m =1350cm
(h) height of wall=1.6m=160cm
(b) breadth of wall =60cm
volume = l*b*h
=1350*160*60
=12960000cm³
(l) length of brick =22.5cm
(b) breadth of brick=12cm
(h) height of brick =8cm
volume = 22.5*12*8
=2160cm³
no. of bricks = volume of wall/volume of bricks
=12960000/2160
=6000
