Question

A wall of length 10 m was to be built across an open ground. The height of the wall is 4 m and thickness of the wall is 24 cm. If this wall is to be built up with bricks whose dimensions are 24 cm 12 cm 8 cm, how many bricks would be required

Answer 1

dimensions of the wall are L=10=1000cm,H=4m=400cm and thickness (B)=24cm and
dimensions of brick are l=24cm,b=12cm and h=8cm
no.of bricks required=volume of the wall/volume of each brick=1000×400×24/24×12×8=125×100/3=4166 approximate

Answer 2

Step-by-step explanation:

Answer:

◗ Wall Dimension :

Length ( L ) = 10 m = 1000 cm

Breadth ( B ) = 24 cm

Height ( H ) = 4 m = 400 cm

⠀

◗ Bricks Dimension :

Length ( l ) = 24 cm

Breadth ( b ) = 12 cm

Height ( h ) = 8 cm

Number of Bricks Required ?

$\underline{\bigstar\:\textsf{According to the given Question :}}$

$:\implies\sf Vol. \:of \:Bricks \times Number = Vol. \:of \:Wall\\\\\\:\implies\sf l \times b \times h \times Number = L \times B \times H\\\\\\:\implies\sf 24 \times 12 \times 8 \times Number = 1000 \times 24 \times 400\\\\\\:\implies\sf Number = \dfrac{1000\times24 \times 400}{24 \times 12 \times 8}\\\\\\:\implies\sf Number = \dfrac{1000 \times 50}{12 }\\\\\\:\implies\sf Number = 4166.67\\\\\\:\implies\underline{\boxed{\sf Number \approx4167}}$

⠀

$\therefore\:\underline{\textsf{B) \textbf{4167 Bricks} would be required for wall}}.$
