To allocate the joint costs to product DBB-1 using the physical measure method, we follow these steps:
1. Determine the total units produced:
[tex]\[
\text{Total units produced} = 16,000 + 24,000 + 36,000 = 76,000 \text{ units}
\][/tex]
2. Calculate the proportion of units produced by DBB-1:
[tex]\[
\text{Proportion of DBB-1} = \frac{\text{Units produced for DBB-1}}{\text{Total units produced}}
\][/tex]
[tex]\[
\text{Proportion of DBB-1} = \frac{16,000}{76,000} = 0.2105
\][/tex]
3. Calculate the joint cost allocated to DBB-1:
[tex]\[
\text{Joint cost allocated to DBB-1} = \text{Total joint cost} \times \text{Proportion of DBB-1}
\][/tex]
[tex]\[
\text{Joint cost allocated to DBB-1} = 3,600,000 \times 0.2105 = 757,895
\][/tex]
Therefore, the amount of joint costs allocated to product DBB-1 using the physical measure method is:
[tex]\[
\boxed{757,895}
\][/tex]
