To convert the given weights into grams, we need to convert each unit to grams and then sum them up.

1. Convert kilograms (kg) to grams (g):
\[ 8 \text{ kg} = 8 \times 1000 \text{ g} = 8000 \text{ g} \]

2. Convert dekagrams (dag) to grams (g):
\[ 4 \text{ dag} = 4 \times 10 \text{ g} = 40 \text{ g} \]

3. The grams (g) are already in the correct unit:
\[ 35 \text{ g} \]

Now, add all the converted values together:
\[ 8000 \text{ g} + 40 \text{ g} + 35 \text{ g} = 8075 \text{ g} \]

So, \( 8 \text{ kg } 4 \text{ dag } 35 \text{ g} = 8075 \text{ g} \).
