A cuboid whose length, breadth and height are 15 mm, 10 mm and 20 mm respectively, then its lateral surface area would be:

A cuboid whose length, breadth and height are 15 mm, 10 mm and 20 mm respectively, then its lateral surface area would be: Correct Answer 1000 mm<sup>2 </sup>

The lateral surface of an object is the area of all the sides of the object, excluding the area of its base and top.

If we take the length of the cuboid as l, breadth as b and the height as h, then

Lateral surface area of a Cuboid = 2(lh + bh) = 2h(l + b)

A = (2 × 20)(15 + 10) = 1000 mm2

Use 1 cm = 10 mm
