SURFACE AREA AND VOLUME

ACKNOWLEDGEMENTI would like to express my special thanks of gratitude to my teacher MRS. SAVITRI P.N. who gave me this golden opportunity to do this wonderful project, which also helped me in doing a lot of research and I came to know about so many new things. I am not doing this project for marks but to enhance my knowledge. Thank you once again ma’am.

SURFACE AREASurface area is the total area of the faces and curved surface area of a solid figure like CUBE, CUBOID, CYLINDER etc.

VOLUMEVolume is the measure of the amount of space inside a solid figure like a CUBE,SPHERE,CONE, CYLINDER etc. ITS UNIT IS ALWAYS ‘CUBIC’.

SURFACE AREA

AND VOLUME OF

A CUBOID

The surface area of a cuboid is: 2( lb. + bh +hl )

VOLUME OF A

CUBOID

Is= l*b*h

cubic

units

SURFACE AREA AND

VOLUME OF A CUBE

The surface area of a cube is 6a2

VOLUME OF A CUBE IS a3

CURVED SURFACE AREA,TOTAL

SURFACE AREA AND VOLUME

OF A CYLINDER

Curved Surface Area=2(π)r*h

Total Surface Area =2πr(h + r)

Volume of a Cylinder= πr2h

CURVED SURFACE AREA, TOTAL

SURFACE AREA AND VOLUME

OF A CONE

Curved Surface Area of a CONE=(π)*r*l

Total Surface Area of a Cone

= C. S. A + area of base

= (π)*r*l + (π)r*r= (π) r (l + r) sq. units

Volume of a Cone=1/3 (π)r2h

SURFACE AREA

& VOLUME OF A SPHERE

SURFACE AREA OF A SPHERE = 4 (π)r2

VOLUME OF A SPHERE= 4/3 (π)r3

Curved Surface Area,

Total Surface Area and

Volume of a Hemisphere

Curved Surface Area of a hemisphere= 2(π)r2 Surface Area of a hemisphere= 3(π)r2

Volume of a hemisphere= 2/3(π)r3
