1) pit dimensions are
length =L =1.4 m =1.4 *100cm=140cm
breadth =B =90cm
height =H = 70cm
2) each brick dimensions are
l=21cm
b=10.5cm
h=?
1000* volume of one brick = volume of mud dug from pit
1000* 21*10.5*h = 140 *90*70
h = (140*90*70)/(1000*21*10.5)
after cancellation
h=14*9*7/10*21*105
h= 4cm
therefore height of each brick =h = 4cm
length =L =1.4 m =1.4 *100cm=140cm
breadth =B =90cm
height =H = 70cm
