Having problems with surface area of a triangular prism. I know the formula is ab + (S1 + S2 + S2)h, however I can't tell what all 3 sides of the trianle are from the picture. The triangular face shows a height of 50 in and a base of 20 in. No other measurements are given on the triangle. The rectangular face of the prism is showing the width of 45 with no other measurements given. Not sure how to solve with only 3 numbers given.
