The office building is 48 floors high. half of the floors have 18 windows each and half of the floors have 36 windows each. how many windows does the building have in all?

1296 windows

Step-by-step explanation:

HALF of the floors, means

HALF of 48, that is:

48 * 0.5 = 24

Thus, we can say:

24 floors each have 18 windows, and

24 floors each have 36 windows

Total Number of Windows:

24 * 18 = 432 windows

24 * 36 = 864 windows

Total = 432 + 864 = 1296 windows

Answer:

1296 windows are present in the building

Explanation:

Given the office building is 48 floors high

Half of floors have 18 windows each

Then , half of floors = = 24 floors

Total windows on half of the floors, that is 24 floors

Also, half of the floors have 36 windows each

Total windows on rest half floors (24 floors)

=

= 864 windows

Total windows = 432 + 864 = 1296 windows
