C2 EDEXCEL MATHS 25TH May 2016

Hi, does anyone know all the formulae for volume or area that we need to know for c2 as there may be some unexpected shapes that we have to calculate. Thanks
yeah, learn the surface area and volume of a sphere, cuboid, cylinder and possibly a cone (probably not)

You need to know how to work out the volume and area of a cuboid and cylinder and some 2D shapes

Cylinders crop up a lot

Volume=
Ο€r^2h
Surface area=
2Ο€rh+2Ο€r^2
(Where r= radius of the circular face, and h=height of the cylinder longways)

What's surface area of a cuboid? Get it confused sometimes thanks

Just find the surface area of each of the rectangular faces, which is an area of a rectangle and add them up.

Volume of Cuboid = 2(LB + BH + LH)

L= Length
B=Breadth
H=Height

How to remember: Learn By Heart ----> LBH

I hope this helps.
