uhammad, a shipping and receiving clerk, uses 1 yard, 2 feet, 4 inches of twine to wrap each carton he packs. He has to pack 29 cartons today. How much twine will he need? Convert the answer to larger units whenever possible.

Answer 1

Answer: 58 yards of twine is needed to wrap 29 cartons .

Explanation:

Length of twine to wrap each carton = 1 yard 2 feet 4 inches

As we know that

$1\ yard=3\ feet$

And

$1\ feet=12\ inches$

So, we have

$3\ feet+2\ feet+12\ inches\\\\=5\ feet+12\ inches\\\\=5\times 12+12\ inches\\\\=60+12\ inches\\\\=72\ inches$

Number of cartons he has to pack = 29

Now, length of twine he will needed for 29 cartons is given by

$72\times 29=2088\ inches$

As we need to change it into larger units i.e. yards

So,

$2088\ inches=58\ yards$

Hence, 58 yards of twine is needed to wrap 29 cartons .
