* * * Similarity: Three-dimensional space has height. Similarity between cylinder and prism;
They are all cylinders, and the volume can be calculated by the general formula of cylinder volume: volume = bottom area × height.
2。 The difference between a cone and a pyramid is that one face of the pyramid is a polygon and the other faces are triangles with a common vertex. The cone is surrounded by a circular bottom and a fan-shaped side.
If a cone (pyramid or cone) has a base area of S and a height of H, its volume is V-cone = 1/3Sh.
If the radius of the cone bottom is r and the height is h, then its volume is: V cone = 1/3π r2h.
Similarities: they are all cones, and the bottom surface corresponds to a vertex.
