what are the formulas in finding the surface area of a cube, cylinder, sphere, prism, cone and a pyramid?

Answer 1

cube--- A three-dimensional figure with
six congruent square sides.
a = b = c
d = a sqrt(3)
T = 6a2
V = a3
Face diagonal a sqrt(2)

cylinder
Height: h
Area of base: B
Length of lateral edge: l
Area of right section: A
Perimeter of right section: P

Lateral surface area: S
Total surface area: T
Volume: V
S = lP
T = lP + 2B
V = hB = lA
sphere
Radius: r
Diameter: d
Surface area: S
Volume: V

S = 4 Pi r2 = Pi d2
V = (4 Pi/3)r3 = (Pi/6)d3
prism
Height: h
Area of base: B
Length of lateral edge: l
Area of right section: A
Perimeter of right section: P

Lateral surface area: S
Volume: V
S = lP
V = hB = lA
cone
Height: h
Area of base: B
Volume: V

V = hB/3
pyramid
Height: h
Area of base: B
Slant height: s (regular pyramid)
Perimeter of base: P
Lateral surface area: S
Volume: V

S = sP/2 (regular pyramid)

V = hB/3

Answer 2

Cylinder and Prism = base area x height (base area of both sides may be added)
Cone and Pyramid = 1/3 x base area x height (Base area may be added)
Cube = 6 x base area
Sphere = 4 x cirle area
