Yes? I see that this figure has 5 sides: 2 identical triangular ends and 3 rectangular sides. Think: what is the formula for the area of a triangle? Use it to find the area of one end of this prism; then multiply your result by 2. What is the formula for the area of a rectangle? Please show me what you can do in figuring these various areas.
