Answer :
Explanation :
Since the wall with all its bricks makes up the space occupied by it, we need to find the volume of the wall, which is nothing but a cuboid.
Here,



Therefore,


Now, each brick is a cuboid with Length = 24 cm, Breadth = 12 cm and height = 8 cm.
So,


So,



Therefore,
- <u>The wall requires 4167 bricks. </u>
You would multiply 48 by 6, giving you 288 windowpanes
Step-by-step explanation:
lim(n→∞) |aₙ₊₁ / aₙ|
lim(n→∞) | (4ⁿ⁺¹ / (n+1)!) / (4ⁿ / n!) |
lim(n→∞) | (4ⁿ⁺¹ / (n+1)!) × (n! / 4ⁿ) |
lim(n→∞) | 4 / (n+1) |
0
Since the limit is less than 1, the series converges.
