We have to find the surface area of rectangular prism.
It has 6 surfaces the two bases with dimensions 12 cm x 8cm = 96 cm^2
Surface area of the two surfaces=2 * 96 cm^2=192 cm^2
Surface area of two vertical surfaces with dimensions 12 * 9= 2*108 cm^2=216
Surface area of vertical surface with dimensions 8cm x 9 cm=2*72 cm^2=144
Total surface area= 96+216+144=456 cm^2
