Calculating the Total Mass of Five Boxes of Cookies

To determine the total mass of five boxes of cookies, we can use the given information that three boxes of cookies weigh 7.2 kg.

According to the provided information, 3 boxes of cookies weigh 7.2 kg. We can use this information to calculate the mass of five boxes of cookies.

Using the given information, we can set up a proportion to find the mass of five boxes of cookies:

3 boxes of cookies = 7.2 kg 5 boxes of cookies = ? (to be calculated)

We can use the proportion 3 boxes of cookies is to 7.2 kg as 5 boxes of cookies is to x kg and solve for x.

Using the proportion, we can calculate the mass of five boxes of cookies as follows:

3 : 7.2 = 5 : x

Solving for x: 3/7.2 = 5/x x = (5 * 7.2) / 3

Calculating the value of x: x = 12

Therefore, the mass of five boxes of cookies is 12 kg.
