Volume and Surface formula for solids, sphere, prism, cuboid:

Cuboid Formula:

Let’s consider the length of the cuboid is p units, breadth is a units and height is s units. Then,

a. Volume = (p x a x s) cubic units

b. Surface Area = 2 (pa + as + ps) square units

c. Diagonal = √(p2 + a2 + s2) units

 

Cube Formula:

If each edge of a cube is considered to be of length x, then

a. Volume = x3 cubic units

b. Surface Area = 6x2 square units

c. Diagonal = √3x units.

 

Cylinder Formula:

Let the radius of base = I, height or length = m. Then,

a. Volume = ∏l2m cubic units

b. Curved Surface Area = 2∏lm square units.

c. Total Surface Area = 2∏l (l + m)

 

Cone Formula:

Let the radius of base = l and height or length = m. Then,

a. Slant height S = √(l2 + m2) units

b. Volume = 1/3 (∏l2m) cubic units

c. Curved Surface Area = ∏lm square units

d. Total Surface Area = (∏lm + ∏l2) square units

 

Sphere Formula:

If the radius of the sphere r, Then

a. Volume = 4/3 (∏r3) cubic units

b. Surface Area = (4∏r2) square units
