crushed or cubes?

Susan prepared cold Ribena for her son's birthday party. She wanted the drink to remain cold for as long as possible. 

Q: Which type of ice, cubes or crushed, should she use?

A: Ice cubes. They have less surface area in contact area with the drink than crushed ice. So they will melt more slowly.  BUT they will also cool the drink more slowly.
