Surface Area and Volume
Surface area and volume formulas for right rectangular prisms S=surface area V=volume l=length w=width

S=2lw+2lh+2wh and V=lwh

Volume S=6s2 and V=s3

7.2 Surface Area and Volume of Prism
Surface Area of a Right Prism S=surface area L=lateral area B=base H=height

S L+2b or you can use Shp+2b Volume=Base x height



7.3 Surface Area and Volume of Pyramids
Surface Area of a Regular Pyramid S=surface area L=lateral area B=base V=volume

Volume V=1/3Bh
 * S=**L + B **or S**1/2//l//p + B
