Answer 2

Calculating the Empty Box's Mass

To find the mass of the empty box, we can use the information provided. Let's denote the mass of the empty box as x kg, the total mass of the box with the cookies as 15 kg, and the mass of the box filled halfway with cookies as 8 kg.

We can set up the following equation to solve for x: 15 - 8 = x

By solving this equation, we can find the mass of the empty box.

Calculation

The mass of the empty box is 7 kg.

This calculation is based on the given information that the mass of the box filled halfway with cookies is 8 kg and the total mass of the box with the cookies is 15 kg.

Therefore, the mass of the empty box is 7 kg.
