Scott is ordering 6 bags of cat food from canada. each bag has a mass of . to determine the shipping costs, scott needs to know
OLEGan [10]

The weight of the cat food in pounds is 99 lbs.

<h3>What is a pound?</h3>

The pound, sometimes known as pound-mass, is a unit of mass that is used in both the British imperial and American customary measurement systems.

<h3>How do we convert kg to pounds?</h3>

You multiply a weight by the conversion factor 2.2046 to change a mass measurement from kilograms (kg) to pounds (lbs).

Given that,

Mass of each bag = 7.5 Kg.

Number of bags bought = 6

Firstly, we need to find how much the cat food weighs:

Total weight of cat food = 6 × 7.5

Total weight of cat food = 45kg

Next, we will require to convert the kg into pounds:

1kg = 2.2lb

45 kg = 45* 2.2

45 kg = 99 lbs

Therefore, the weight of the cat food in pounds id 99lbs.
