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 = \(\frac{6930000}{1000}\)
= 6930 Litres
