Question

A rectangular pit of dimensions 30mx15mx12m is dug and the earth
taken out is disposed off in a carrier which can carry a maximum load of
540m3 of earth. The least number of rounds the carrier had to make to
dispose off the earth dug out is ________​

Answer 1

100

Step-by-step explanation:

$volume \: of \: earth \: dug = 30 \times 15 \times 12 \\ = 54000 \: {m}^{3} \\ volume \: carried \: in \: 1 \: round \: = 540\: {m}^{3} \\ least \: number \: of \: rounds = \frac{54000}{540} = 100$
