Surface Area of a Triangular Prism 2
 1) Find the area of the triangular base. To find the surface area of a triangular prism: 2) Multiply the area of the triangle by 2. 3) Find the area of each of the three rectangular sides. 4) Add them all up.  Areas of rectangular sides = 10 x 3 + 8 x 3 + 6 x 3 = 30 + 24 + 18 = 72cm2 Area of the triangles= 24 x 2 = 48 cm2 Surface Area = 72 + 48 = 120 cm2 8 cm 6 cm 10 cm 3 cm  Find the surface area of the triangular prism: Surface area = unit2 12  3 cm Find the surface area of the chocolate: Surface area = cm2 10 cm 3 cm 2 cm  Surface Area = in2 Find the surface area of the alarm clock: 4 in 3 in 7 in 4  Surface Area = ft2 Find the surface area of the prism: 4ft 3 ft 5ft 10 ft  Find the Surface Area of the Prism cm2  Find the Surface Area of the Prism ft2  cm2 Find the Surface Area |
