Question

how many bricks will be required to construct a wall 1300cm long,600cm high and 20cm thickif each brick measure(25cm,13cm,10cm)

Answer 1

Hi there !!

Dimensions of the wall :
Length = 1300cm
Breadth = 600cm
Height = 20cm

Volume of the wall = length × breadth × height
Volume = 1300cm × 600cm × 20cm
Volume = 15600000cm³

Dimensions of the brick :
Length = 25cm
Breadth = 13cm
Height = 10cm

Volume of the brick = length × breadth × height
Volume = 25cm × 13cm × 10cm
Volume = 3250cm³

Number of bricks that will fit in the wall

$= \frac{volume \: of \: wall}{volume \: of \: each \: brick}$

$= \frac{15600000cm {}^{3} }{3250cm {}^{2} }$

= 4800

Thus,

4800 bricks will be required
