Answer:
9 boxes cost Rs 405
Step-by-step explanation:
1 box costs 45.
so, how much are 2 boxes ? what do you think ?
right, twice as much : 2 × 45 = 90
how much are 3 boxes ?
now it is three times the cost of 1 box : 3 × 45 = 135
do you see the pattern ?
it is really simple.
that is also the origin why we describe a multiplication by "times". we take a single item so and so many times.

therefore,
9 × 45 = 405
