Answer 1

Step-by-step explanation:

The wall,

l=10 m =1000 cm

b= 24 cm

h=4 m =400 cm

Then the volume is =( 1000×24×400) cc

=9600000 cc

the volume of the brick is = (12×24×8)cc

=2304 cc

Then number of bricks are= 9600000/2304

=4167

Answer 2

Answer:

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 ?

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

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

⠀

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