A tank at present is 0.875 phone which is 21 litres how much water does the tank hold when full

What the dickens is " 0.875 phone"?

wondering the same thing!!!

To find out how much water the tank holds when full, we need to determine the tank's capacity per unit of length.

Given that the tank is currently at 0.875 phone, and its capacity at that level is 21 litres, we can calculate the capacity per unit of length.

Capacity per unit of length = Capacity at current level / Current level

Capacity per unit of length = 21 litres / 0.875 phone

Now, we can determine the capacity of the tank when it is full by multiplying the capacity per unit of length by the desired level.

Capacity when full = Capacity per unit of length * Desired level

Since we want to know how much water the tank holds when full, the desired level would be 1 (since that represents full capacity).

In this case, the capacity when the tank is full would be:

Capacity when full = Capacity per unit of length * 1

Therefore, to find out how much water the tank holds when it's full, you need to calculate the capacity per unit of length and multiply it by 1.
