Question

Playing dice generally come in the shape of a
A. square
B. rectangle
C. cube
D. cuboid

Answer 1

Hint: We first try to describe what a dice is and what are its specialities. We find that the dice has to be a three-dimensional object. We then try to match it with the given options. We can eliminate two of them as they are two-dimensional figures. We use the concept of equal sides of a cube to find the correct option for the problem.

Complete step-by-step answer:
Playing dice generally come in the shape of a cube.

Here we have been given four options. We will first describe each option and then we find the correct one.
The playing dice is a three-dimensional object. We use it in real life. It has 12 sides of equal length. It also has 6 faces with numbers 1 to 6 written over it using representations like a dot for one digit. The probability of a number appearing in a roll of a dice is always $\dfrac{1}{6}$.
For our first two options out of those given four options are two-dimensional figures. Square and rectangle both can be drawn on paper in a two-dimensional space. They have length and breadth only.
The rest of the two options cube and cuboid are three-dimensional objects. But the difference between these two is that in the case of a cube all the dimensions are of equal length unlike cuboid where the dimensions are of different value. A Cube is a special case of cuboid.
Dice itself has 12 equal sides. So, it can’t be cuboid. The remaining option is cube. That’s why the correct option is C.

So, the correct answer is “Option C”.

Note: We need to equate the characteristics of the dice’s sides being equal, to find the correct option for the problem. This type of dice is called unbiased dice. The dice can be of any colour and usually contains markings shaped like dots on its faces, where one dot represents 1 number. But, the shape would always be that of a cube.
