A cloud engineer is configuring a cost estimate in the Google Cloud Pricing Calculator for a high-availability database cluster operating continuously in `us-central1` for a $730$-hour month.

The target architecture consists of the following components:
1. Compute Engine: $10$ `custom-2-8` VM instances (each with $2$ vCPUs and $8\text{ GB}$ of RAM).
- Base rate per vCPU: $\$0.033174$ per hour.
- Base rate per GB RAM: $\$0.004446$ per hour.
- Sustained Use Discount (SUD): Instances run $100\%$ of the month, qualifying for an effective $30\%$ discount on total compute costs ($0.70$ multiplier).
2. Storage: Each of the $10$ instances uses a $200\text{ GB}$ Extreme Persistent Disk (`pd-extreme`) provisioned with $2,500\text{ IOPS}$ per disk.
- Capacity rate: $\$0.125$ per GB per month.
- Provisioned IOPS rate: $\$0.025$ per provisioned IOPS per month.
3. Network Egress: Total internet data egress from `us-central1` to North America is $500\text{ GB}$ per month.
- First $100\text{ GB}$ per month: $\$0.00$ per GB (free tier).
- Next $400\text{ GB}$ ($101\text{ GB}$ to $500\text{ GB}$): $\$0.12$ per GB.

What is the net total monthly cost in USD for this workload? (Round your final answer to two decimal places.)
