Question

13. A tall office building has 80 floors. Each floor
has 50 windows. Each window is to be
decorated with 60 tiny bulbs. How many bulbs
would be needed to decorate all the windows?​

Answer 1

Step-by-step explanation:

no of bulbs = 80(50)(60)

= 240000

Answer 2

Answer:

2,40,000 tiny bulbs

Step-by-step explanation:

Total number of windows will be - 80x50 = 4,000

Now, we got 80 floors will have 4,000 windows.

4,000x 60 (the number of tiny bulbs needed)

So, 4,000x60= 2,40,000

Hence 2,40,000 bulbs will be needed to decorate all the windows.
