Question

The surface area of the cuboid as shown below is sq. in.

• A. 60
• B. 72
• C. 84
• D. 96

Answer 1

The correct option is B 72

Given :
Length of cuboid(l) = 6 in

Width of cuboid(w) = 2 in

Height of cuboid(h) = 3 in


$\therefore \text{Surface area of cuboid = 2lw + 2 wh + 2 hl}$
$=(2\times 6\times 2)+(2\times 2\times 3)+(2\times 3\times 6)$

$=24+12+36$
$=72\text{sq. in}$

<!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> ∴ Surface area of the cuboid = 72 sq.in
