18 cases
Math:
each tile is 5in X 5in = 25 square inches per tile
25 square inches per tile X 75 tiles per box = 1875 square inches per case
1875 square inches per case / 144 square inches per square foot = 13 square feet per case
225 square feet in the room / 13 square feet per case = 17.3 cases or 18 full cases.

In square close-packed layer, a molecule is in contact with four of its neighbours. Therefore, the two-dimensional coordination number of a molecule in square close-packed layer is 4.
I will assume that the question is to find the maximum number of balls that could be packed into the space and that each ball must be kept intact. 1 inch = 25.4 mm (exactly) 1 mm = 1/25.4 inches = 0.03937007874015748031496062992126 The standard ping pong ball is 40mm in diameter according to the link 40 mm * 0.03937007874015748031496062992126 = 1.5748031496062992125984251968504 inches in diameter 12 feet = 12 feet*12 inches per foot = 144 inches (in reference to the room's dimensions) We lay the balls end to end along one wall to see how many fit. 144/1.5748031496062992125984251968504 inches = 91.44 At most, 91 whole balls will fit in this space. We now come to the complication that has to do with how the balls might be packed together efficiently (known as the sphere packing problem). For this solution, I will assume that the balls are not packed in an offset manner (the centers of which would form hexagons), but rather are in a configuration where the centers of the balls form a lattice like structure similar to the integer locations on the usual Cartesian Coordinate system. (One difficulty proving the packed solution is that to be clear, one probably needs the ability to enter images into the answer, something that currently is not allowed.) Therefore, I will simply proceed with the assumption that no offsetting of the balls takes place. 91 balls in each of the 3 directions of the cube gives 91*91*91=753,571 total balls. Notice that one cannot simply calculate the number of balls in a cubic foot and then multiply by the number of cubic feet in the room. That is because the balls don't fit exactly into the cubic foot and the extra space accumulates as more cubic feet are utilized.
A ratio says how much of one thing there is compared to another thing. There are 3 blue squares to 1 yellow square Ratios can be shown in different ways: Using the ":" to separate the values: 3 : 1 Instead of the ":" you can use the word "to": 3 to 1 Or write it like a fraction: 3 1 A ratio can be scaled up: Here the ratio is also 3 blue squares to 1 yellow square, even though there are more squares.
Square density refers to the number of squares or square units that can fit within a given area. It is a measure of how closely packed squares are within a specific space or region. Mathematically, square density can be calculated by dividing the total number of squares by the total area.

huge, I know about it Not really. It's only about 3 inches tall, and maybe 1.5 inches wide (3 inches when keyboard tray is expanded). It's a fairly small phone for all the technology packed inside.
Cheetahs do not have a maximum number of spots. The number of spots would depend on the size of the cheetah and how closely packed the spots are.
Packing density... refers to the number of components 'packed' into a single micro-chip.
