The dimensions of a rectangular water tank are 2 m 75 cm by 1 m 80 cm by 1 m 40 cm. How many litres of water does it hold when filled to the brim?

We know that,

1m = 100 cm


Therefore,


Dimensions of the tank will be: 2m 75cm × 1m 80 cm × 1m 40cm


= 275 cm × 180 cm × 140 cm


We know that,


Volume of cuboid = Length × Breadth × Height


= 275 × 180 × 140


= 6930000 cm3


We also know that,


1000 cm3 = 1L


Therefore,


Volume =


= 6930 Litres
