How to work out total bond interest expense?

[Shakey_101]

Brace Ltd issued five-year debentures (bonds) with a face value of $1 million and a contract rate of interest of 10% per annum. The amount received from the issue was $926,405, ensuring an effective rate of interest of 12% per annum. Interest is payable semi-annually on 30 September and 31 March.

Determine the total bond interest expense to be recognized over the bonds' life.

Please explain the answer so that I can see how it's done.

Thanks
