Solution

For one student, rice needed $= 150 g m$
For $40$ students, rice needed $= 150 \times 40 g m$
$= 6000 g m$
$= 6 k g$

For one student, oil needed $= 15 m l$
For $40$ students, oil needed $= 15 \times 40 m l$
$= 600 m l$

Hence, the total rice needed is $6 k g$ and the total oil needed is $600 m l$ .
