The tide depth in Deep Cove, B.C., from midnight to 12:00 PM on January 10, 2011, can be modeled by the polynomial function f(t)=-0.002t^3+0.212t^2+0.748t+2.699

where f(t) is the tide depth in meters and t is the number of hours after midnight

Use the polynomial function to determine the tide depth, to the nearest tenth of a metre, at 08:00 AM on January 10.
