Answers: 2
![The\ volume\ of\ the\ cube:V=a^3\ (a-length\ of\ an\ edge)\\\\V=343 cm^3\to a^3=343cm^3\to a=\sqrt[3]{343cm^3}\to \boxed{a=7cm}\\\\because\ 7^3=343\\-------------------------------\\\\the\ surface\ area\ of\ the\ cube:A_S=6a^2\\\\therefore\\\\A_S=6\cdot7^2=6\cdot49=\boxed{294\ (cm^2)}](/tpl/images/0202/5019/9bb91.png)
