How do you find a surface area of a prism
Asked by admin @ in Mathematics viewed by 324 People
How is the process of finding the surface area of a rectangular prism the same as finding the surface area of a triangular prism? How is it different?
ANSWER:
For both prisms, you can draw a net to help you find the areas of the faces. Add the areas together to find the surface area. A rectangular prism has only rectangular faces, and you use the formula bh to find area. A triangular prism has triangular and rectangular faces, and you use the area formula bh for rectangular faces and the area formula 1/2bh for triangular faces.
