📝 Answered - A cube has a volume of 216 cubic centimeters. What can be concluded about this cube? Check all that apply. Recall the formula for a cube: [tex]$V = s^3$[/tex]. * The side length, s, can be found using the equation [tex]$3s = 216$[/tex]. * This is a perfect cube. * The side length is 72 centimeters. * The side length is 6 centimeters. * Taking the cube root of the value will determine the side length. * If you multiply the volume by three, you can determine the side length.
