    Answer:

    Volume=1280cm^3\\Area=768cm^2

    Step-by-step explanation:

    Side length ‘a’ of the Prism= 8 cm

    Height(h)= 20 cm

    Volume of a square prism:

                               Volume  Side*Side*Height\\\\                                     = a*a*h\\\\                             = 8*8*20 \\\\                       = 64*20\\\\                          =1280cm^3

    Surface area of Square prism :

                             Surface area   2a^2+4ah\\\\                                             2(8*8)+4(8)(20)\\\\                                             2(64)+4(160)\\\\                                              128+640\\\\                                              =768 cm^2
