Answer:
80 in^2
Step-by-step explanation:
Surface area = sum of all the faces of a 3d figure
SA = 2(lw + hw + hl) l=length w=width h=length
(This is technically finding the area of all the faces and adding them up)
2(4 x 3 + 4 x 3 + 4 x 4)
2(12 + 12 + 16)
24 + 24 + 32
48 + 32
80 in^2
have a great day! :D
