Search: if the edge of a cube is doubled, the volume

Number of results: 2,182

math
If you count the tip as an edge, the bottom circular portion is another edge. However, the tip is not an edge, so the correct answer is still one. I hope this helps a little more. Thanks for asking.

It is edge (or circumference) per dollar you want, not area in this case so divide each circumference by the cost to find the edge per dollar. (I do not agree that the edge is the best, but so be it)

MATH!
If the edge of a cube is increased by 50%, then the volume is increased by x%. Find x. PLEASE HELP. THANK YOU. Let Y = edge of a cube. Y + 0.5Y = 1.5Y = new edge of the cube. Then old volume is Y^3 New volume is (1.5Y)^3 = 2.375Y^3. %increase = ([3.375Y^3 - Y^3]/Y^3) x 100 = x...
