Use paper and pencil to total the surface area. On a triangular prism you can add up the surface areas if you know them. Each triangle has an area of 6 square meters (sq m). Each triangular surface has an area of 10 square meters (sq m). What is the surface area of this figure? 42 sq m 36 sq m 26 sq m 16 sq m On a triangular prism you can add up the surface areas if you know them. Each triangle has an area of 6 square meters (sq m). Each triangular surface has an area of 10 square meters (sq m). What is the surface area of this figure? 42 sq m On a triangular prism you can add up the surface areas if you know them. 30+12= 42 10 +10+10 = 30 two triangles three rectangles 6+6=12 ![]() Thanks for stopping! |
