A certain cube floating in a bucket of water has between 60 and 85 percent of its volume below the surface of the water. If between 9 and 26 cubic centimeters of the cube's volume is above the surface of the water, then the length of a side of the cube is approximately
Select the correct option: A) 4 B) 5 C) 7 D) 8 E) 9
If sides are 7, vol=7^3=343   60%= 205.8, 85%=291.55   so vol above water, between 137.2 and 51.45 --&gt;too big   If side are 4, vol = 64   60%=38.4, 85%=54.4   vol above water between 25.6 and 9.6   So 4 should be the answer.   Check option C,   If sides are 5, vol = 125   60%= 75, .85%=106.25   vol above water between 18.75-50   (Sides are 4 cubic centimeters)   4
