AI Thread Summary
To estimate the number of books that can be shelved in a college library with 3500 square meters, one must consider the dimensions of the space, including the width of the corridors and the size of the shelves. Assuming an average book size and that shelves are 8 high with books on both sides, the calculation involves determining the effective shelving area after accounting for 1.5-meter-wide corridors. The dimensions of the library do not need to be square, but knowing the width of the room will help in calculating how many shelves can fit. Clarification on shelf dimensions is necessary for a more accurate estimate. Overall, understanding the layout and dimensions is crucial for determining shelving capacity.

Homework Statement


25) Estimate how many books can be shelved in a college library with 3500 square meters of floor space. Assume 8 shelves high, having books on both sides, with corridors 1.5m wide. Assume books are about the size of this one, on average.

From there I'm kind of stuck, please help..

Does the room have to be a square? If so calculate the dimensions of the square. If you know the width of the room and the total width of each shelf/corridor then you know how many shelves/corridors can fit into the room. That's a good start at least. Where you gettin tripped up?
 
I'm not sure how big the shelves are though.
 
TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
Thread 'Variable mass system : water sprayed into a moving container'
Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
