Answer:
[tex]264\ in^2[/tex]
Step-by-step explanation:
The total are of cuboid with length of [tex]l[/tex] inches, width of [tex]w[/tex] inches and height of [tex]h[/tex] inches is
[tex]SA=2(lw+lh+wh)\ in^2[/tex]
In your case,
[tex]l=8\ in\\ \\w=6\ in\\ \\h=6 \ in[/tex]
Thus,
[tex]SA=2(8\cdot 6+8\cdot 6+6\cdot 6)\\ \\=2(48+48+36)\\ \\=2\cdot 132\\ \\=264\ in^2[/tex]
