Answer :

To find the number of inches in [tex]\( 6 \frac{3}{4} \)[/tex] feet, follow these steps:

1. Convert the whole feet portion to inches:
Each foot contains 12 inches.
Therefore, [tex]\( 6 \)[/tex] feet is:
[tex]\[ 6 \times 12 = 72 \text{ inches} \][/tex]

2. Convert the fractional feet portion to inches:
To find how many inches are in [tex]\( \frac{3}{4} \)[/tex] of a foot, multiply [tex]\( \frac{3}{4} \)[/tex] by 12 inches (since one foot contains 12 inches):
[tex]\[ \frac{3}{4} \times 12 = 9 \text{ inches} \][/tex]

3. Add the two quantities together:
Adding the inches from the whole feet and the fractional part:
[tex]\[ 72 + 9 = 81 \text{ inches} \][/tex]

Therefore, the total number of inches in [tex]\( 6 \frac{3}{4} \)[/tex] feet is:
[tex]\[ \boxed{81} \][/tex]
