Question

What is the lateral surface area of the cuboid shown below?

• A. 280 unit square
• B. 160 unit square
• C. 100 unit square
• D. 60 unit square

Answer 1

The correct option is B 160 unit square

We know that the lateral surface area of a cuboid $=2\times h\times (l+b)$
Where, $l$ is the length of the cuboid, $b$ is the breadth of the cuboid, and $h$ is the height of the cuboid.

For the cuboid given above:
l = 10 units
b = 6 units
h = 5 units
On substituting the values, we get:
Lateral Surface Area of Cuboid = $2\times 5\times (6+10)=160$ unit square
