How many faces, edges and vertices of a triangular prism
What is missing length of rectangular prism if height and width are both 8 inches. And surface area is 256 in^2
Write formula for surface area of triangular prism.
Surface area of a square pyramid is 160cm^2. The area of the lateral triangles is 96cm^2. What is length of one of the sides.
What 2d shape do you get from a cross section of a triangular prism perpendicular to it’s base?
- A triangular prism has 5 faces, 9 edges, and 6 vertices.
- The missing length of the rectangular prism would be the length, as the formula for surface area of a rectangular prism is A = 2lw + 2lh + 2wh, where l = length, w = width, h = height, and A = surface area.
- The formula for surface area of a triangular prism is SA = 2(base area) + (perimeter of base) * (height)
- If the area of the lateral triangles is 96cm^2 and the surface area of the square pyramid is 160cm^2, then the area of the base is 64cm^2. Since it is a square pyramid, each side of the base would be √64 cm = 8cm.
- The 2D shape you get from a cross-section of a triangular prism perpendicular to its base would be a triangle.
