The passenger section of a train has a width 2x-7, length 2x + 3 , and heigh x-2, with all dimensions in metres. Solve a polynomial equation to determine the dimensions of the section of the train if the volume 117m^3.

So do u first times the L x W x H to get the polynomials and the bring the 117 to the other side ( left side ) and then solve and get the factor?
