calculate the surface area of each prism.
length 9cm
width 4cm
hieght 8cm

math 
Samantha,
Vanessa,
the answer should be 288cm. for the surface area all you do is multiply lenght width and height

math (correction) 
PsyDAG,
Length * Width * Height = Volume rather than surface area.
What shape is the prism?
