Answer 2

Mensuration

The dimensions of empty tank is $40\ cm\ by\ 30\ cm\ by\ 24\ cm$.

Number of small containers which she pours is 10.

The capacity of each small container is $2.8 \ litres$.

According to question,

Volume of larger tank $= 40 \ cm \times30\ cm\times 24\ cm=28800 cm^3$.

A s we know that,

$1000 cm^3=1 liter\\\\\implies 28800\ cm^3=28.8 \ liter$

The amount of water she already poured into the tank = $2.8\times 10=28\ liter$.

Quantity of water needed more to fill the tank = $28.8-28=0.8 \ litres$.

Hence, 0.8 litres of water is needed to fill the tank fully.
