Answer:
Height of stack = 14 feet and 3 inches
Step-by-step explanation:
Height of boxes are given as following:
1) 5 feet 9 inches
2) 5 feet 12 inches
3) 2 feet 7 inches
The boxes are stacked together one on top of each other.
So height of stack = sum of heights of all the boxes
⇒ [tex](5+5+2)\ feet + (9+7+11)/ inches[/tex]
⇒ [tex]12\ feet + 27\ inches[/tex]
We know that [[tex]1\ feet =12\ inches[/tex]]
So, we to convert inches to feet we divide by 12 and write the remainder in inches.
⇒ [tex]12\ feet + \frac{27\ inches}{12}[/tex]
So, the quotient of [tex]\frac{27\ inches}{12}[/tex] would be =2 feet and remainder =3 inches
We have,
⇒ [tex]12\ feet + 2\ feet + 3\ inches[/tex]
⇒ [tex]14\ feet \ and\ 3\ inches[/tex]
So, height of stack = 14 feet and 3 inches
