The meter is the SI unit of length, but the base unit of the cgs system is the centimeter.

The lengths of two rods are $20.123cm$ and $18.1cm$ that are placed end to end.

Find:

The combined length of the two rods.

Solution:

The length of the first rod A be $20.123cm$.

The length of the second rod B be $18.1cm$.

When the rods are joined end to end.

The combined length of the rods will be:

Length of A + Length of B $=20.123cm+18.1cm=38.223cm$.

The combined length of the rods is $38.223cm$.
