Question

How many bricks will be required to built a wall 8 m long, 6 m high and 22.5 cm thick measure 25cm by 11.25 cm by 6cm

Answer 1

total brick required = total volume of wall / total volume of 1 brick

$n= \frac{total \: volume \: of \: wall}{total \: volume \: of \: a \: brick}$

n = 8×100×6×100×22.5/(25×11.25×6)

= 6400 bricks
