Here's the solution to the frustum problem: Given Information: Frustum of a right pyramid with rectangular base ABCD. AB = 12 cm, BC = 9 cm. Top rectangular face EFGH with EH = 8 cm. Height of the frustum (h) = 10 cm. Part (a): Find the length of GH. Step 1: Determine the ratio of similarity between the top and bottom bases. Since the frustum is from a right pyramid with a rectangular base, the top face EFGH is similar to the bottom face ABCD. The ratio of corresponding sides is constant. We can use the sides EH and BC. Ratio
