Question

The length, breadth and height of a cuboid are 10 cm, 12 cm and 15 cm. Find the lateral surface area of the cuboid.

• A. $660c{m}^2$
• B. $550c{m}^2$
• C. $260c{m}^2$
• D. $440c{m}^2$

Answer 1

The correct option is A $660c{m}^2$

Lateral surface area of a cuboid $=2(l\times h)+2(b\times h)$
$=2(10\times 15)+2(12\times 15)$
$=2\left(150\right)+2\left(180\right)$
$=300+360$
$=660c{m}^2$
