Asked by Olivia
The bases of a triangular prism are equilateral triangles. The surface area of the prism is 80 square units. If the area of one of the triangular bases is half the area of one of the rectangular faces, what is the area of one of the triangular bases of the prism?

base area = B
face area = 2B
total surface (two bases + 3 faces):
2B + 3(2B) = 80
face area = 2B
total surface (two bases + 3 faces):
2B + 3(2B) = 80
