Answer 1

137.16cm

- - - - - - - - - - - - - - - - - - - - - - - -

Here's how it works:

If there are 2.54 centimeters in an inch and 12 inches in a foot, then there is 30.48 cm in a foot.

- - - - - - - - - - - - - - - - - - - - - - - -

2.54 x 12 = 30.48

Now, multiply that by 4.

30.48 x 4 = 121.92

Now the 4 feet is taken care of. 6 inches to go:

2.54 x 6 = 15.24

Add:

121.92 + 15.24 = 137.16
