Answer 1

Answer:

$= 100$

Step-by-step explanation:

TSA of brick → 2(L×b+b×h+h×l)

$= 2(22.5× 10 + 10 \times 7.5 +7.5 \times 22.5)$

$= 2 (225 +75 + 168.75) cm²$

$=2 ( 468.75) cm ²$

$= 937.5cm²$

$= \frac{937.5 {cm}^{2} }{100 \times 100}$ $=0.09375 m²$

Therefore, Required number of Bricks-

$= \frac{9.375 {cm}^{2} \times 100}{0.09375 \: {cm}^{2} }$

$= 100$

• Hence,The required Number of Bricks = 100 respectively.
