What is the surface area of the triangular prism? 5cm. 11cm, 3cm, 4cm
The surface area of a triangular prism can be calculated by finding the area of each face and adding them together.
The triangular faces have a base of 4 cm and a height of 3 cm, so the area of one triangular face is (1/2) * 4 * 3 = 6 cm^2. Since there are two triangular faces, the total area of both triangular faces is 2 * 6 = 12 cm^2.
The rectangular faces have dimensions of 5 cm by 11 cm, so the area of each rectangular face is 5 * 11 = 55 cm^2. Since there are two rectangular faces, the total area of both rectangular faces is 2 * 55 = 110 cm^2.
Adding the areas of the triangular faces and rectangular faces gives a total surface area of 12 + 110 = 122 cm^2.
Therefore, the surface area of the triangular prism is 122 cm^2.
