It seems reasonable that either a tall, narrow box or a short, flat box could be
formed having the desired volume. Because the taller box is preferred, larger
initial estimates of the height are reasonable. However, heights greater than 20
cm are not physically possible because the metal sheet is only 40 cm wide. Initial
estimates of 10 and 20 cm are therefore appropriate.

Now check the quality of this solution — that is, whether it returned an exact
root — by looking at the value of the previous estimate of the root (in the Y–register)
and the value of the equation at the root (in the Z–register).
