Find and interpret surface area of prisms and cylinders.

Add the face areas from a net

Problem

A net for a triangular prism shows \(5~\text{faces}\). The \(\text{two}~\text{triangular}~\text{ends}\) each have an area of \(12~\text{square}~\text{units}\). The \(\text{three}~\text{rectangular}~\text{faces}\) have areas \(40~\text{square}~\text{units}\), \(50~\text{square}~\text{units}\), and \(60~\text{square}~\text{units}\). Find the prism’s total surface area.
