In this article the very last equation has been corrected to display brackets instead of question marks. It now shows as displayed below. The original article has been corrected.

$${V_{sc}}\, = \,\left[ {\left( {\frac{1}{2}\, \times \,12} \right)\, \times \,\left( {\frac{1}{2}\, \times \,12} \right)\, \times \,3\, + \,{4^2}} \right]\, \times \,4\, \times \,\frac{{11}}{{21}}\, = \,259\, + \,\frac{2}{3}\, + \,\frac{1}{7}$$
