Cone
volume=1/3 pi*r^2 *h
area =pi*r*l
total area=pi*r*l+pi*r*r
-----------------
cylinder
volume = pi*r^2*h
area=2*pi*r*h
volume=2*pi*r*h+2*pi*r^2
------------------------------------
sphere
volume=4/3 pi *r^3
area =4*pi*r^2
hemisphere
volume=2/3*pi*r^3
curved area=2*pi*r^2
total area=3*pi*r^2
------------
cube
volume=(side)^3
area=6*a^2
diagonal =square root of 3 *a
-------------------
cuboid
volume=lenght*breadth*height
area =2(l*b+b*h+h*l)
diagonal = squareroot of (l^2+b^2+h^2)
