Answer:
[tex]Volume=1280cm^3\\Area=768cm^2[/tex]
Step-by-step explanation:
Side length 'a' of the Prism= 8 cm
Height(h)= 20 cm
Volume of a square prism:
Volume [tex]Side*Side*Height\\\\ = a*a*h\\\\ = 8*8*20 \\\\ = 64*20\\\\ =1280cm^3[/tex]
Surface area of Square prism :
Surface area [tex]2a^2+4ah\\\\ 2(8*8)+4(8)(20)\\\\ 2(64)+4(160)\\\\ 128+640\\\\ =768 cm^2[/tex]
