Question

How to find the area perimeter and volume of shapes?

Answer 1

• Square

1. Area = s^2
2. Perimeter = 4s

• Rctangle

1. Area = l × b
2. Perimeter = 2(l + b)

• Cube

1. TSA (total surface area) = 6a^2
2. CSA (curved surface area) = 4a^2
3. Volume = a^3

• Cuboid

1. TSA (total surface area) = 2(lb + bh + hl)
2. CSA (curved surface area) = 2h(l + b)
3. Volume = l × b × h

• Circle

1. Circumference = 2πr
2. Area = πr^2

• Sphere

1. CSA = 4πr^2
2. TSA = 4πr^2
3. Volume = 4/3πr^3

• Hemisphere

1. CSA = 3πr^2
2. TSA = 2πr^2
3. Volume = 2/3πr^3

• Cylinder

1. CSA = 2πrh
2. TSA = 2πr(r+h)
3. Volume = πr^2h

• Cone

1. CSA = πrl
2. TSA = πr(r+l)
3. Volume = 1/3πr^2h

• Frustum

1. CSA = π(R1+R2)l
2. TSA = π(R1+R2)l + πr1^2+r2^2
3. Volume = 1/3πh(r1^2+r2^2+r1r2)
