Question

How many centimetres make 1 m?
A. \[10\;{\rm{cm}}\]
B. \[100\;{\rm{cm}}\]
C. \[1\;{\rm{cm}}\]
D. \[0.01\;{\rm{cm}}\]

Answer 1

Hint:The above problem can be resolved using the concept of international standard units available to measure any object's linear dimensions. Moreover, it is known that every parameter is calculated using some units, for which the length is being measured in terms of meters and centimetres. And the appropriate conversion needs to be analysed.

Complete step by step answer:
The centimetre is considered as the one of the unit to measure the length or the dimension of any obstacle provided. On the other hand the metre is the standard SI unit for the determination of the dimensions of the object or the space.
In mathematical sense, One metre consists of hundred centimetres. And it is given as,
\[1\;{\rm{m}} = 1\;{\rm{m}} \times \dfrac{{100\;{\rm{cm}}}}{{1\;{\rm{m}}}} = 100\;{\rm{cm}}\]
Therefore, \[100\;{\rm{centimetres}}\]makes one metre and option B is correct.

Note:The knowledge of the fundamental quantities and the derived quantities needs to be understood to resolve the given problem. The meters, as well as the centimeters, are the units that are used to undertake the linear measurements. For example, The length of a block can be given in terms of meters as well as centimeters, The dimensions of any house or the farm are shown in meters or the centimeters, just like that there are some fundamental units known as International Standard Units or commonly called SI units, which is required to know for basic variables used in the field of physics.
