- Calculate the area of each face of the triangular prism.
- Sum the areas of all faces to find the total surface area.
- For each prism, identify the two triangular bases and three rectangular lateral faces.
- Use the formula for the area of a triangle: (base × height) / 2.
- Use the formula for the area of a rectangle: length × width.
- Add the areas of the two triangles and three rectangles for each prism.
Parent Tip: Review the logic above to help your child master the concept of surface area of a triangular prism worksheet with answers.
