Hi, struggling to answer this question. Can anyone help?

[FONT=&quot]The surface area, [/FONT]S[FONT=&quot], of a cube is directly proportional to the [/FONT]square[FONT=&quot] of the length of its side. The mass, [/FONT]M[FONT=&quot], of the cube is directly proportional to the [/FONT]cube[FONT=&quot] of the length of its side. Work out an equation of proportionality that relates [/FONT]S[FONT=&quot] to [/FONT]M[FONT=&quot].

The answer is S=kM^2/3

M has been raised to the power of two-thirds[/FONT]

Hi, struggling to answer this question. Can anyone help?

The surface area, S, of a cube is directly proportional to the square of the length of its side. The mass, M, of the cube is directly proportional to the cube of the length of its side. Work out an equation of proportionality that relates S to M.

The answer is S=kM^2/3

M has been raised to the power of two-thirds

Can you write that statement as an algebraic equation?
