Answer:
The answer is below
Step-by-step explanation:
A triangular prism is a polyhedron (three dimensional shape) made up of two equal triangles, two equal rectangle and a base rectangle.
The total surface are of a triangular prism is given as:
A = bh + 2ls + lb
where b is the base of the triangle, h is the height of the triangle, l is the length of the base rectangle and s is the length of the slant side of the triangle.
Given that:
b = 6 ft, s = 5.5 ft, h = 5 ft, l = 9 ft.
Therefore:
A = (6 * 5) + 2(9 * 5.5) + (9 * 6) = 183 ft²
Therefore 183 ft² of fabric is needed to make the tent
