Question

A water is flowing through the tap at the rate of 50 cm^3/s. What is the time requires to fill the container of dimensions 20cm * 10cm * 10cm?

(a) 40 seconds

(b) 30 seconds

(c) 45 seconds

(d) 50 seconds

This question was addressed to me in an interview for job.

Query is from Volume of a Cuboid in chapter Surface Areas and Volumes of Mathematics – Class 9

Answer 1

Correct choice is (a) 40 seconds

For explanation: Volume of the container = 20 * 10 * 10

= 2000cm^3

Time required to fill the container = \(\frac{Volume \,of \,container}{Flow \,rate \,of \,water}\)

= 2000/50

= 40 seconds.
