ACKNOWLEDGEMENT I, PRIYANKA BANSAL of class x-c, completed this power point presentation about SURFACE AREAS AND VOLUMES under the guidance and supervision of Mrs. ANAMITA ROY ma’am with a lots of useful and valuable formulae and geometric 3Dimensional shapes.

Slide 4: 

CONE

Slide 5: 

Curved Surface Area of a cone: Пrs Total Surface Area of a cone: Пrs +Пr2 Surface area

Slide 6: 

Volume of a cone: 1/3 Пr 2h volume

Slide 7: 

CUBOID

Surface area : 

Surface area Total Surface Area of a Cuboid: 2(lb +bh +lh) Curved Surface Area of a Cuboid: 2(bh +lh)

VOLUME : 

VOLUME Volume of a Cuboid: length × breadth × height

Slide 10: 

CUBE

Surface area : 

Surface area Curved surface area of a cube: =4×side2 Total surface area of a cube: =6×side2

VOLUME : 

VOLUME Volume of a cube: side3

Slide 13: 

CYLINDER

Surface area : 

Surface area Curved surface area: 2Пrh Total surface area: Пrh +2Пr2 =2Пr(h+r)

VOLUME : 

VOLUME Volume of a cylinder: Пr2h

Slide 16: 

Sphere

SURFACE AREA : 

SURFACE AREA Surface area of a sphere: 4Пr2

VOLUME : 

VOLUME Volume of a sphere: 4/3Пr 3

Slide 19: 

Hemisphere

SURFACE AREA : 

SURFACE AREA Curved surface area of a hemisphere: 2Пr 2 Total surface area of a hemisphere: 3Пr 2

VOLUME : 

VOLUME Volume of A cube: 2/3 Пr 3

Slide 22: 

FRUSTUM

SURFACE AREA : 

SURFACE AREA Curved Surface Area Of A Frustum: П(r+R)l Total Surface Area Of A Frustum: П(r+R)l + Пr 2 + ПR 2 =П(r+R)l + П(r 2+ R2)

VOLUME : 

VOLUME Volume Of A Frustum: 1/3 Пh(r 2+R 2+Rr)
