The box has a square base, so we have V= x^2(h). The volume is 864cm^3. So we have the equation 864=x^2(h). Solving the volume equation for h, we get?

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.

so what is the problem what are they asking you to solve
