l Can we call cube and cuboid as right prisms?
l Have you observed cuboid and cube are also right prisms as their lateral faces
are rectangular and perpendicular to base.
l We know volume of cuboid is product of area of base and height = lb×h
Incube = S3
Hence volume of right prism = Area of base × height
l If base is an equilateral trangle then its volume × a2×h where 'a' is side of
triangle.
l Like prism, pyramid is also a solid figure, An example of pyramid is the
Egyptian pyramids, one of the seven wonders of the world.
l Major difference is that the prism has Lateral faces along with top and base.
Whereas pyramid has Lateral faces with base and vertex at top.
