ANSWER: <em><u>D. Icosahedron</u></em>
(-6)*(-6)*(-6)=-216.
Therefore, the cubed root of -216 is -6.
Let's represent Ben's current age by x and his age in 16 years, x+16.If in 16 years, his age will be 3 times his age now, the equation is x+16=3x
x+16=3x
x-x+16=3x-x
16=2x
16/2=2x/2
8=x
Therefore Ben is 8 years old.
