Estimate how many books can be shelved in a college library with 3500 m2 of floor space. assume 8 shelves high, having books on both sides, with corridors 1.5 m wide. assume books are approximately 25 cm deep and 5 cm wide, on average.

This college library would hold approximately

Knowing that every square meter of floor space occupied by shelves is in reality eight (because of being 8 shelves high) square meters of shelve space where to put books and that the average area of a book is

Having all the necessary data, we estimate how many books would this college library hold:

As it is an estimate, we round it up to the nearest hundred-thousand, i.e., approximately [tex]6*10^{5}/tex] books can be shelved on this library

step-by-step explanation:

let pq = qr = rs = x, and xz = y and zu = z.

if the horizontal lines are parallel, then corresponding segments are in proportion:

substitute:

therefore 3 = y = z.

xu = y + z → xu = 3 + 3 = 6
