**Estimating the Amount of Sugar Required to Make 2894 Cups of Tea**

To estimate the amount of sugar required to make 2894 cups of tea, we can start by calculating the amount of sugar needed for one cup of tea and then multiply it by the number of cups.

**Calculating the Amount of Sugar for One Cup of Tea**

Given that a teaspoon of sugar weighs approximately 4g, and a cup of tea requires 2 teaspoons of sugar, we can calculate the amount of sugar for one cup as follows:

- One cup of tea requires 2 teaspoons of sugar.
- Therefore, the amount of sugar for one cup of tea is 2 x 4g = 8g.

**Estimating the Total Amount of Sugar for 2894 Cups of Tea**

To estimate the total amount of sugar required to make 2894 cups of tea, we can multiply the amount of sugar for one cup by the number of cups:

- Total amount of sugar = Amount of sugar per cup x Number of cups
- Total amount of sugar = 8g x 2894 cups

Now, let's calculate the total amount of sugar required.

- Total amount of sugar = 8g x 2894 cups
- Total amount of sugar = 23152g

**Converting Grams to Kilograms**

To convert the amount of sugar from grams to kilograms, we need to divide the value by 1000 since there are 1000 grams in one kilogram:

- Total amount of sugar in kilograms = 23152g ÷ 1000
- Total amount of sugar in kilograms = 23.152kg

Therefore, an estimated amount of 23.152 kilograms of sugar is required to make 2894 cups of tea.

**Summary**

To estimate the amount of sugar required to make 2894 cups of tea, we calculated the amount of sugar for one cup of tea (8g) and then multiplied it by the number of cups. The estimated total amount of sugar required is 23.152 kilograms.
