Answer 1

Answer:

$264\ in^2$

Step-by-step explanation:

The total are of cuboid with length of $l$ inches, width of $w$ inches and height of $h$ inches is

$SA=2(lw+lh+wh)\ in^2$

In your case,

$l=8\ in\\ \\w=6\ in\\ \\h=6 \ in$

Thus,

$SA=2(8\cdot 6+8\cdot 6+6\cdot 6)\\ \\=2(48+48+36)\\ \\=2\cdot 132\\ \\=264\ in^2$
