Given the available information, how do you find the FV of reinvested coupons using excel functions?

The answer is:

* FV of reinvested coupons, % of par [26.26]

Total accumulated, % of par [128.76]

Annualized total return [6.41%]

My question is mainly about the first one as I could not figure it out.
