<s>[INST] The figure below is a rectangular prism. The length, width, and height are L, W, and H, respectively.
The figure is rotated so that W and H are the new length and width. Thus, the new volume V of this prism is given by the equation V = L * W * H.
 Now, if L = 15 and W = 18, the height is unknown. But if the new volume equals the original volume, what is the new height H given that H is calculated  using the equation H = (L * W * H /(L * W) = L * H / W?[/INST]
