Problem Analysis

To find the total weight of cookies in the box, we need to calculate the weight of one pack of cookies and then multiply it by the total number of packs in the box.

Calculation

Given: - The weight of one pack of cookies is a grams. - There are 4 layers of packs in the box. - Each layer has b rows. - Each row has 7 packs of cookies.

To find the weight of one pack of cookies, we can use the value of a.

To find the total weight of cookies in the box, we can multiply the weight of one pack by the total number of packs in the box.

Let's calculate the weight of one pack of cookies and then find the total weight of cookies in the box.

Calculation Steps

1. Calculate the weight of one pack of cookies: - The weight of one pack of cookies is a grams.

2. Calculate the total number of packs in the box: - The number of packs in each layer is b rows * 7 packs per row. - The total number of packs in the box is 4 layers * the number of packs in each layer.

3. Calculate the total weight of cookies in the box: - The total weight of cookies in the box is the weight of one pack * the total number of packs in the box.

Let's substitute the given values and calculate the weight of cookies in the box.

Calculation Example

Given: - a = 100 grams - b = 5

1. Calculate the weight of one pack of cookies: - The weight of one pack of cookies is 100 grams.

2. Calculate the total number of packs in the box: - The number of packs in each layer is 5 rows * 7 packs per row = 35 packs. - The total number of packs in the box is 4 layers * 35 packs = 140 packs.

3. Calculate the total weight of cookies in the box: - The total weight of cookies in the box is 100 grams * 140 packs = 14,000 grams.

Therefore, the total weight of cookies in the box is 14,000 grams.

Please note that the given values of a and b were used in this example. If you have different values for a and b, you can substitute them into the calculations to find the weight of cookies in the box.
