1. Problem Description

The problem requires us to convert 4 yards into inches. We need to find the number of inches that are equivalent to 4 yards.

2. Solution Steps

We know the following conversion factors:

$1 \text{ yard} = 3 \text{ feet}$

$1 \text{ foot} = 12 \text{ inches}$

Therefore,

$1 \text{ yard} = 3 \text{ feet} = 3 \times 12 \text{ inches} = 36 \text{ inches}$

To convert 4 yards to inches, we multiply 4 by the number of inches in 1 yard.

$4 \text{ yards} = 4 \times 36 \text{ inches}$

$4 \times 36 = 144$

So, $4 \text{ yards} = 144 \text{ inches}$

3. Final Answer

144
