Cube has same sides Vertical surface area of

Cube has same sides Vertical surface area of cube = 4(side)2

Total Surface area of cube 2 = 6 (side)

Volume of Cube 3 = (side)

Vertical Surface Area of Rectangular Parallelepiped =2(l+b)h

Total Surface area Rectangular Parallelepiped = 2 ( l x b +b x h + h x l )

Volume of Rectangular Parallelepiped = l x b x h

Base Area of 2 Curved surface cone = r area of cone = rl

Total surface area of cone = r (l+r)

Volume of cone = 1/3 2 r h

Right circular cylinder

Base area of Right Circular 2 Cylinder = r

Bottom area of Right Circular Cylinder = r 2

Curved Surface area of Right Circular Cylinder = 2 rh

Total Surface area of Right Circular Cylinder = 2 r(r+h)

Volume of Right 2 Circular Cylinder = r h

Sphere • Curved surface area of sphere = 4 r 2

• 4 Volume of sphere = / 3 3 r

Curved surface area of hemisphere = 2 r 2

Total surface area of hemisphere = 3 r 2 2 r 2

Volume of hemisphere = 2/ 3 3 r
