Solid geometry formula

1, prism surface area A=L*H+2*S, volume v = s * h. (l: bottom perimeter, h: column height, s: bottom area)

2. The surface area of a cylinder is a = l * h+2 * s = 2π * r * h+2π * r 2, and the volume is v = s * h = π * r 2 * h..(L: perimeter of bottom surface, H: column height, S: area of bottom surface, R: radius of bottom surface circle).

3. The surface area of the sphere is a = 4π * r 2, and the volume is v = 4/3π * r 3. (r: radius of sphere)

4. Cone surface area a = 1/2 * s * l+π * r 2, volume v =1/3 * s * h =1/3 π * R2 * h ... (s: length of cone bus, l: circumference of bottom, r:.

The surface area of the pyramid is A= 1/2*s*L+S, and the volume is v =1/3 * s * h (s: the height of the side triangle, l: the perimeter of the bottom, s: the area of the bottom, and h: the height of the pyramid).

Mathematically, solid geometry is the traditional name of geometry in three-dimensional Euclidean space. Stereographic drawing deals with volume measurement of different shapes: cylinder, cone, frustum, sphere, prism, wedge, bottle cap and so on.
