The figure that has 2 triangular faces and 3 rectangular faces is known as a triangular prism. It looks like a standard two-pole tent, or the outer packaging of a bar of Toblerone.The objecta triangular prism.

A polyhedron is a 2 dimensional object. To have fasce it would have to be at least 3 dimensional. If you want to know what is a polyhedron with 4 sides, it's a quadrilateral THAT'S NOT QUITE RIGHT - actually it's completely false. Sorry, Ratty, a polyhedron is a 3 dimensional figure. Polygon refers to 2 dimensional figures. A pyramid with a triangular base is a polyhedron with 4 faces.
To work out the area of the rectangular faces, you need to multiply the length by the width. You then need to multiply that answer by 3 (because there are 3 rectangular faces).To work out the area of the triangular faces, multiply the base of the triangle by the height and divide the answer by 2 (to find the area of one triangle). You then need to multiply it by 2 again because there are 2 triangular faces.Important: The height of a triangle is the distance from the top corner of the triangle down to the base (so that it meets the base at 90 degrees)You then need to add the total surface area of the rectangular faces to the surface area of the triangular faces to get the total surface area of the entire prism.(sorry for the essay :])
A triangular prism has three rectangular faces which, between them, will have 4*3 = 12 right angles. It also has two triangular faces and these can have another 2 right angles. So the answer is 12 or 14, depending on whether the triangles are right angled or not.
