1. Cube

Let side of a cube be s.

Then, commit to memory the following formulas in the cube

Lateral surface area = 4s^{2}

** Total surface area = 6s ^{2} **

** Volume = s ^{3} **

** Diagonal = s × √3 **

2. Cuboid

Let l, b and h denote the length, breadth and height of a Cuboid respectively.

** Then, commit to memory the following formulas in the cuboid**

** Lateral surface area = 2 (lh + bh) {lh = l × h, bh = b × h} **

** Total surface area = 2 (lb + lh + bh) **

** Volume = l × b × h **

** Diagonal of a Cuboid is **

3. Right Circular cylinder

Let r and h be radius and height of a right circular cylinder. Then,

Commit to memory the following formulas in a right circular cylinder

Curved surface area = 2rh

Total surface are = 2r^{2} + 2rh = 2r(r + h)

Volume = r^{2}h

4. Circular cone

Let r be radius; h, the vertical height; and l, the slant height in a right circular cone.

** Then, **

Curved surface area = **rl**

Total surface area = **rl + r ^{2}**

Volume =

5. Sphere

** Let ‘r’ denote radius of a sphere. Then, **

Total surface area of the sphere = 4r^{2}

** Volume of the sphere = **

6. Hemi sphere

** Let ‘r’ denote radius of a hemi sphere. Then, **

Curved surface area = 4r^{2}

** Total surface area = 3r ^{2}**

** Volume = **
