Question

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

Answer 1

Solution:-
Given : Length of the rectangular water tank = 2 m 75 cm = 275 cm
Breadth of the rectangular water tank = 1 m 80 cm = 180 cm
Height of the rectangular water tank = 1 m 40 cm = 140 cm
Volume of the water tank = L × B × H 
= 275 × 180 × 140 
Volume of the water tank = 6930000 cu cm
Now, we know that 1 liter = 1000 cu cm
So, capacity of the water tank = 6930000/1000
6930 liters
So, the water tank can hold 6930 liters of water when it is filled to the brim.
Answer.

Answer 2

Solution :

Length = 2.75 m
Breadth = 1.80 m
Height = 1.40 m

Volume : Length X Breadth X Height
= ( 2.75 X 1.80 X 1.40 ) m^3
= 6.93 m^3

1m = 1000 litres
= 1000 X 6.93
= 6930 litres...
