The total surface area of the triangular prism given in the figure and formed by two triangles and three rectangles is equal to 1176 square centimeters.
How to calculate the surface area of the triangular prism
Total surface area is the sum of areas of all faces of a given solid. The total surface area is the surface area of all faces of the triangular prism, which is equal to the sum of the areas of the faces, represented by two triangles of equal area and three rectangles of distinct area:
A = 2 · (14 cm) · (12 cm) + (15 cm) · (20 cm) + (13 cm) · (20 cm) + (14 cm) · (20 cm)
A = 1176 cm²
