Surface Area of a Rectangular Prism .
Surface area is the area of the surface on a rectangular prism .
Surface area = Length x height
= 2cm x 2cm = 4squaredcm
= 4squaredcm x 2 = 8squarecm
= 6cm x 2cm = 12squarecm

= 12squarecm x 4 = 48squarecm
Surface area = 48squarecm

The volume of a rectangular prism is how much space it takes up .
Volume of rp = length x width x height
length = 6cm
width = 2cm > 6 x 2 x 2 = 24squarecm *
height = 2cm
Volume of rp = 24squarecm
