a submerged styrofoam rectangle with size H 100cm x L 15cm x W 50 cm. the object is submerged at 20 meters (60ft) underwater. it will be rising upward with the top side (750cm^2 area )

based on formula for drag, i need to calculate how long it will take to surface at the top, and what is its speed.

big thank you in advance...
