Cube
Volume= a3 [a=side of a cube]Total surface area= 6a2
Longest Diagonal of the cube= a√3
Cuboid
Volume= l*b*h [where l=length b=breadth h=height] Total surface area= 2*[l*b ! b*h ! l*h]Longest Diagonal= √ "l2 ! b2 ! h2#
Cylinder
Volume= $r 2h%ur&ed surface area'lateral surface area= 2$rhTotal surface area= 2$r*"r!h#
Hollow Cylinder
Volume= $*"( 2 ) r 2#*hTotal surface area= 2$(h ! 2$rh ! 2$* "( 2 r 2#
Cone
Volume= +'3 * $ * r 2 * h%ur&ed ,urface -rea= $rlTotal ,urface -rea= $r*"r!l#
Sphere
Volume= .'3 * $ * r 3
Total ,urface -rea= .$r 2
Hemisphere
Volume= 2'3 * $ * r 3
Total ,urface -rea= 3$r 2
