The possible dimensions of the prism will be evaluated as follows:
<span>60x3 + 145x2 + 70x
factoring out 
factoring out 5x we get:
5x(12x^2+29x+14)
factoring the quadratic we get:
5x(3x+2)(4x+7)
hence the dimensions are:

\bf R=-0.028(t)+20.8~~ \begin{cases} R=seconds\\ t=\stackrel{1920+}{years}\\ ------\\ R=18.0 \end{cases}\implies 18=-0.028t+20.8 \\\\\\ 0.028t=20.8-18\implies 0.028t=2.8\implies t=\cfrac{2.8}{0.028}\implies t=100 \\\\\\ \stackrel{\textit{since \underline{t} is years since 1920}}{1920+100\implies 2020}
