Question

how many bricks will be required for a wall which is 8m long ,6 m high and 22.5 cm thick, if each brick measures 25 cm × 11.25 cm × 6cm?​

Answer 1

GIVEN :

$↪ \sf \: length \: = 8 \: m$

$↪ \sf breadth \: = 22.5 \: m$

$↪ \sf \: height = 6 \: m$

SOLUTION :

$↪ \sf \: length \: of \: the \: wall = (8 \times 100)cm = 800 \: cm$

$↪ \sf \: breadth \: of \: the \: wall = 22.5 \: cm$

$↪ \sf \: height \: of \: the \: wall = (6 \times 100)cm = 600 \: cm$

FORMULA :

$\sf↪ \: volume \: of \: the \: wall = (l \times \: b \times h)$

$↪ \sf \: volume \: of \: the \: wall = (800 \times 22.5 \times 600)cm ^{3}$

$↪ \sf \: volume \: of \: 1 \: brick = (25 \times 11.25 \times 6)cm ^{3}$

NUMBER OF BRICKS

REQUIRED :

$↪ \sf \: = \dfrac{volume \: of \: the \: wall}{volume \: of \: one \: brick} = ( \dfrac{800 \times 22.5 \times 600}{25 \times 11.25 \times 6} )$

$↪ \sf \: = 6400$

${\boxed {\red {\sf{Hence \: 6400 \: bricks \: will \: be \: required \: for \: a \: wall.\: }}}}$
