Question

The lateral surface area of a cuboid with length 5 cm, breadth 4 cm, and height 3 cm is .

• A. $54c{m}^2$
• B. $45c{m}^2$
• C. $44c{m}^2$
• D. $55c{m}^2$

Answer 1

The correct option is A $54c{m}^2$

Given that,
length is 5 cm, breadth is 4 cm and height is 3 cm.

We know that,
lateral surface area of cuboid
$=2h(l+b)$

Now,
lateral surface area
$=2\times 3(5+4)$
$=54c{m}^2$
