Important Formulas to Remember (Chapter 13: Surface Areas and Volumes)

Here is a well-organized list of formulas divided by shape:

1. Cuboid

• Surface Area = 2(lb + bh + hl)
• Volume = l × b × h

2. Cube

• Surface Area = 6a^2
• Volume = a^3

3. Cylinder

• Curved Surface Area = 2πrh
• Total Surface Area = 2πr(h + r)
• Volume = πr^2h

4. Cone

• Curved Surface Area = πrl
• Total Surface Area = πr(l + r)
• Volume = (1/3)πr^2h

5. Sphere

• Surface Area = 4πr^2
• Volume = (4/3)πr^3

6. Hemisphere

• Curved Surface Area = 2πr^2
• Total Surface Area = 3πr^2
• Volume = (2/3)πr^3

7. Frustum of Cone

• Volume = (1/3)πh(r1^2 + r2^2 + r1r2)
• Curved Surface Area = π(r1 + r2)l
