To determine the height (h) of the triangular face of the tent, we would typically need more information about the dimensions of the triangle, such as the lengths of the sides or the base and area of the triangle.
Without specific measurements or a diagram related to the triangular face of the tent, I'm unable to calculate or provide a definitive answer to what the value of h should be.
If you can provide the necessary measurements or clarify the shape and dimensions of the triangular face, I would be happy to help with the calculations!
