the function x(A)= sqrt A/6 can be used to determine the side length, x, of a cube given the surface area of the cube, A. The function V(x)= x^3 can be used to find the volume of a cube. how can these functions be combined
It can be achieved by substituting the formula for length i.e x(A) = A/6 into the formula for Volume. in the diagram( please mind my writing) the x(A) is substituted into V(x) . Only thing left is substitution of the values . hope this helps .
