Question

how many bricks each measuring 25 CM length 11 point 25 cm height 6 CM thickness will be needed to build a wall 8 M long 6 M and 25.5 M thick

Answer 1

wall;
l=8m=800cm
h=6m=600cm
b=22.5cm
volume of the wall=lbh
=800*600*22.5
=10800000centi metre cube
brick;
l=25cm
b=11.25cm
h=6cm
volume=lbh
=25*11.25*6
=1687.5 centi metre cube
therefore number of bricks=volume of wall/volume of 1 brick
= 10800000/1687.5
=6400 bricks
therefore number of bricks is 6400 bricks
Hope this helps you !!
