Given:

It has rained $276\ mm$ in the last 3 days.

To do:

We have to find the rainfall of one full week in cm, assuming that the rain continues to fall at the same rate.

Solution:

The rainfall in 3 days $= 276\ mm$

Therefore,

The rainfall in one day $= \frac{276}{3}$

$=92\ mm$

We know that,

1 week $=$ 7 days

The rainfall in one full week at the same rate will be $=92\ mm\times7$

$= 644\ mm$

We know that,

$1\ mm = 0.1\ cm$

This implies

$644\ mm = 644\times0.1\ cm$

$= 64.4\ cm$

The rainfall of one full week in cm is $64.4\ cm$
