Given:
Length of the cuboid tank = 4 m
Breadth = 2.5 m
Height = 2.4 m
One third of the tank is filled with water.
1 cubic meter = 1000 liters.
To find:
The quantity of the water in the tank.
Solution:
Volume of a cuboid is:

Where, l is length, b is breadth and h is the height.
The volume of the tank is :


Volume of tank is 24 cubic meter.
One third of the tank is filled with water. So, the volume of the water is

The volume of water is 8 cubic meters.
We have,
1 cubic meter = 1000 liters.
8 cubic meter = 8000 liters.
Therefore, the quantity of the water in the tank is 8000 liters.
Ok so basically your going to subtract 57-8 which is 49. So now you have 7y=49 so now divide 49 by 7 which is 7. So your answer is 7 and to check your work substitute 7 for y so.... 7(7)+8=57 so 57=57 which is accurate
Answer:
Any number between them both
I think the answer would be D 78 hope it helps
