Question
A box has length, breadth and height of 10 cm, 20 cm and 5 cm respectively. The lateral surface area of the box is ______.
Answer: Option C
:
C
Given,
length (l) = 10cm
breadth (b) = 20cm
height (h) = 5cm
Since each side's measurementis different, we can assume itas cuboid.
Lateral surface area of the box (cuboid)
=2h(l+b)
=2×5×(10+20)
=10×30
=300cm2
