Volume and Surface formula for solids, sphere, prism, cuboid:
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
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.
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)
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
If the radius of the sphere r, Then
a. Volume = 4/3 (∏r3) cubic units
b. Surface Area = (4∏r2) square units
