Mensuration 3D Formulas
Here are some important formulas, we must consider while solving mensuration 3D questions.
Shape | Volume Formula | Curved Surface Area Formula | Total Surface Area Formula |
---|---|---|---|
Cube | V = s³ (where s is the length of one side) | CSA = 4s² (where s is the length of one side) | TSA = 6s² (where s is the length of one side) |
Cuboid | V = lwh (where l is the length, w is the width, h is the height) | CSA = 2lh + 2wh (where l is the length, w is the width, h is the height) | TSA = 2lw + 2lh + 2wh (where l is the length, w is the width, h is the height) |
Cylinder | V = πr²h (where r is the radius, h is the height) | CSA = 2πrh (where r is the radius, h is the height) | TSA = 2πr(h + r) (where r is the radius, h is the height) |
Cone | V = (1/3)πr²h (where r is the radius, h is the height) | CSA = πrl (where r is the radius, l is the slant height) | TSA = πr(r + l) (where r is the radius, l is the slant height) |
Sphere | V = (4/3)πr³ (where r is the radius) | CSA = 4πr² (where r is the radius) | TSA = 4πr² (where r is the radius) |
Hemisphere | V = (2/3)πr³ (where r is the radius) | CSA = 2πr² (where r is the radius) | TSA = 3πr² (where r is the radius) |
