Resistance decade box is nothing but Resistance bank. It has various ranges of Resistance value ranging from few ohms to few mega ohms. In other terms, large value of resistance are fabricated in single box is said to be Resistance decade box.
same as decade resitance box but instead of reitances there wil be capacitances
It is used to dial in a specific resistance within the range of the box. It can be used wherever you need a resistor of an unknown value or a precise value. Most decade boxes provide reistance with .01% of the desired resistance. I've used them to balance a wheatstone bridge that had a tiny mV offset.
Resistance box will provide resistance of discrete values such as 1, 2, 3 ohms or 0.1,0.2, 0.3 ohms. So interim values are not possible. But rheostat gives a chance to vary the resistance continuously. It may be 5 ohm or even 5.769 ohm. So just to fix current for a specified value such 1.5 ampere resistance box will not be suitable where as a rheostat is the most suitable.
I have never come across a symbol for an electrical resistance box. As the resistance box is a test instrument and it would not be drawn on any electrical schematic there may not be a symbol designated for it. The last letter of the Greek alphabet is (Ω omega) and it is used for the electrical symbol for resistance.

we use it when we require a variable resistance in a circuit
The use of a resistance box or a "Decade Box" is to help calibrate instruments used to measure electrical values such as Voltage, Current, and Resistance. Without them you would not have a known value of resistance to use as a set point.
A box of precision resistors where you can dial in the exact resistance you want with dials. Essentially a variable resistor with very precise, discrete, settings.

An advantage of cardboard is that cardboard can be made into a box to protect things and is recyclable. A disadvantage of cardboard is that it is easily damaged.

a box which has resistance between 1 ohm to 50000 ohm
It is used to dial in a specific resistance within the range of the box. It can be used wherever you need a resistor of an unknown value or a precise value. Most decade boxes provide reistance with .01% of the desired resistance. I've used them to balance a wheatstone bridge that had a tiny mV offset.
Advantages - not too hard to make, commonly enjoyed taste, usually inexpensive to make (buy a box and icing, for example), fun to bake, fun to decorate, used for celebration (birthday, wedding, ect.) Disadvantages - high in calories, not very nutritious / good for you, can be expensive and complex
They are very simple visual representations of data. Their simplicity is their advantage as well as their disadvantage: they are easy to produce and to understand. But they convey rather a limited amount of information.
yes
