Question

A wall is $22.5$ meter long $10$ meter high and $33$ meter thick. What will be the number of bricks used to build this wall if each brick is $22$ cm $\times 15$ cm $\times 9\times$ cm?

• A. $25,000$
• B. $20000$
• C. $10000$
• D. $15000$

Answer 1

The correct option is A $25,000$

Number of bricks $=\frac{Volumeofthewall}{Volumeofabrick}$
$=\frac{22.5\times 10\times 33}{22\times 5\times 09}$
$=25,000$
