Question

A wall of 15m Length, 9m height, and 0.60m width is being constructed using bricks with dimensions : 18cm × 10cm × 7.5cm. How many bricks will be required to construct the wall ?​

Answer 1

Question:-

• A wall of 15m Length, 9m height, and 0.60m width is being constructed using bricks with dimensions : 18cm × 10cm × 7.5cm. How many bricks will be required to construct the wall ?

━━━━━━━━━━━━━━━━━━━━━━━━━

$\red{\boxed{ \sf \blue{ Understanding\: the \: Question }}}$

• In this question we have to find the Volume of wall and Volume of the bricks , then we have to divide them to find the number of bricks used to construct the wall.

━━━━━━━━━━━━━━━━━━━━━━━━━

Given:-

• Length of the wall = 15m = $\blue{\fbox\orange{1500cm }}$

• Breadth of the wall = 0.60m = $\blue{\fbox\orange{60cm }}$

• Height of the wall = 9m = $\blue{\fbox\orange{900cm }}$

━━━━━━━━━━━━━━━━━━━━━━━━━

Volume of wall = 1500 × 60 × 900 cm³

Volume of brick = 18 × 10 × 7.5 cm³

━━━━━━━━━━━━━━━━━━━━━━━━━

Let's do it :-

$\begin{gathered}\begin{gathered}\begin{gathered}:\green \implies \underline\purple{ \boxed{\displaystyle \sf \bold\red{\: Bricks \: Required \: = \: \frac{Volume\: of \: the \: Wall}{Volume \: of \: 1 \: brick} }} }\\ \\\end{gathered}\end{gathered}\end{gathered}$

$\begin{gathered}\begin{gathered}\begin{gathered}: \implies \displaystyle \sf \: Bricks \: Required \: = \: \frac{1500\: ×\: 60 \: × \: 900}{18 \: ×\: 10 \: × \: 7.5} \\ \\ \\\end{gathered}\end{gathered}\end{gathered}$

$\begin{gathered}\begin{gathered}\begin{gathered}: \green\implies \underline\red{ \boxed{\displaystyle \sf \bold\blue{\: Bricks \: Required \: = \: 60,000 bricks}} }\\ \\\end{gathered}\end{gathered}\end{gathered}$

━━━━━━━━━━━━━━━━━━━━━━━━━

Hence,

The Bricks Required to construct the wall = 60,000

Answer 2

Answer:

Volume of wall = 1500 × 60 × 900 cm³

Volume of brick = 18 × 10 × 7.5 cm³

Length of the wall = 15m = 1500cm

Breadth of the wall = 0.60m = }60cm 

Height of the wall = 9m = }900cm 

above answer is correct dude..
