9. The formula for the volume \( V \) of a triangular prism is given by the equation \( V = \frac { 1 } { 2 } b h \ell \) , where \( b \) is the base of the triangle, \( h \) is the height of the triangle, and \( \ell \) is the length of the prism. Solve the formula for \( b \) . Justify each step. Then find the base of a prism with a volume of \( 128 \) cubic meters, a height of \( 8 \) meters, and a length of \( 4 \) meters.
