Basic Formula

Volume

Cube=E^3

Rectangular Prisim=L*W*H

Sphere=4/3π*R^3

Triangular Prisim=(1/2B)H

Cylinder=(πR^2)H

Cone=1/3(πR^2)H

Pyramid=B*H*1/3 (where "B" equals the area of the base)

In trigonometry the acronym SOH CAH TOA represents:

sin=opposite/hypotenuse 
cos=adjacent/hypotenuse 
tan=opposite/adjacent

Concentration=M/100cm^3 (Mass of the Solute per 100 cm³ of solution)

Density=D=M/V
