Question

write the formula of the volume of a all the 3d solids ​

Answer 1

Answer:

Sphere

Surface area = 4πr2

Volume = 4⁄3πr3

Prism

Surface Area of a Prism = 2 × (Area of the base shape) + (Perimeter of base shape) × (d)

Volume of a Prism = (Area of base shape) × d

Box  

Surface Area of a Box = 2(L × W) + 2(L × D) + 2(W × D)

Volume of a Box = L × W × D

Cube

Surface Area of a Cube = 6a2

Volume of a Cube = a3

Cylinder

Surface Area of a Cylinder = 2πr2 + 2πrh

Volume of a Cylinder = πr2h

Step-by-step explanation:

Answer 2

Answer:

Shapes Volume Formula Variables

Rectangular Solid or Cuboid V = l × w × h

l = Length,

w = Width,

h = Height

Cube V = a3 a = length of edge or side

Cylinder V = πr2h

r = radius of the circular edge,

h = height

Prism V = B × h

B = area of base, (B = side2 or length.breadth)

h = height

Sphere V = (4⁄3)πr3 r = radius of the sphere

Pyramid V = (1⁄3) × B × h

B = area of the base,

h = height of the pyramid

Right Circular Cone V = (1⁄3)πr2h

r = radius of the circular base,

h = height (base to tip)

Square or Rectangular Pyramid V = (1⁄3) × l × w × h

l = length of the base,

w = width of base,

h = height (base to tip)

Ellipsoid V = (4⁄3) × π × a × b × c a, b, c = semi-axes of ellipsoid

Tetrahedron

V = a3⁄ (6 √2)

a = length of the edge
