None of the toothpicks can be removed; all squares have to still connect in some manner; and all toothpicks must be part of a square in the new equation.

square (h) +[hsin(theta)* dh/d(theta)] =1
this can be read as : h square + h into sin theta * differential of h w.r.t. theta = 1
here h is function of theta
h= h(theta)

Jeff is making a toy box for his nephew. He will use pine for the square base and sides, but oak for the top. Pine costs $16/m2 and oak costs $20/m2. If the volume of the toy box is to be 1.3 m3, find the amount of oak that is needed if the cost of all the wood for the toy box is to be as low as possible.
