Question

How many bricks will be required construct wall 13.5m iong , 6cm high and 22.5 cm thick if each brick measures ( 27cm *12.5cm *9cm ) . Maths?

Answer 1

Answer: therefore 1.67 bricks will be required

Answer 2

$\textbf{\underline{\underline{According\:to\:the\:Question}}}$

Length of wall = (13.5 × 100 cm)

= 1350cm

Breadth = 22.5cm

Height = 6 × 100 cm

= 600 cm

★Volume of wall

= (1350 × 22.5 × 600)cm^3

★Volume of each brick :-

= (22 × 12.5 × 9)cm^3

Now :-

Number of brick required

$\tt{\rightarrow\dfrac{Volume\:\:of\:\:wall}{Volume\:\:of\:1\:\:brick}}$

Volume and surface area

$\tt{\rightarrow\dfrac{1350\times 22.5\times 600}{27\times 12.5\times 9}}$

= 6000
