The volume is length x height x width.
You have the height (12 inches) and the width (2 inches) and the volume (204 cubic inches). Put those into the formula for volume and rearrange to solve for length.
V = L x H x W
204 in3 = L x 12 in x 2 in
204 in3 = L x / 24 in2
204 in3 / 24 in2 = L
8.5 in = L
Hope this helps
