Surface Area of a Rectangular Prism:
Surface area is the total area of the prism. The measurements from the net all added up.
Surface Area = lengthxheight
= 4 cm x 4cm = 16cm(2)
=8cmx4cm=32 cm (2)
Then you add them all up.
16+16+32+32+32+32= 160cm(2)

Volume of a Rectangular Prism:
LxWxH
(lengthxwidthxheight)
8x4x16 = 512 cm (2)
base = 96cm(2) ( you add up the three rectangles across the middle )
height = 16 cm(2)
96x16 - 1536
Volume = 1536 cm (2)
