As given in the picture, the formula for a cube's surface area is
, which s is the length of one side of the cube. So let's solve:
<u><em>Answer:</em></u>
Each shelf can hold 20 boxes of cereal.
<u><em>Step-by-step explanation:</em></u>
Start with 80 boxes of cereal: (80)
There are 4 shelves for each box of cereal: (x/4)
Thus, we get the expression: 80/4=
(You may want to simplify this; giving you the answer of 20.)

I'd go with your third option, 6.
Half the diameter (the radius, also the hypotenuse for the right triangle) is 10 units.
Half of the chord given by that blue line segment is 8 units. Now we do the Pythagorean Theorem (a² + b² = c²) to find the length of x.
x² + 8² = 10²
x² + 64 = 100
x² = 36
√x² = √36
x = 6
Answer:
C) The mean is about 100.
Step-by-step explanation:
We see that the best fit line (out of the options listed) would be y=100. The mean can also be algebraically calculated with the following equation:
Let 
be the mean (average) of the values:
, which is closest to answer choice C) The mean is about 100.
