No. This is known to be impossible. For more information, including a proof, check the Wikipedia article on "doubling the cube".
Doubling a cube and trisecting any angle
The Delian Problem, doubling the cube, is considered one of the most famous impossible problems from Greek antiquity. Two others are the trisection of the general angle and the squaring of a circle.

The die you are referring to is actually called a 'doubling cube'; it is one way in which the stakes can be raised in a backgammon match. The use of the doubling cube only makes sense when a backgammon match is played to more than one game. The use of a doubling cube does not necessarily mean that a backgammon match is being played for money.

doubling a cube.
Yes, it is possible.
In a match play event of the "first to x games" variety, when one player gets to within 1 game of winning, the following game is played without the doubling cube (known as the Crawford game). If the player who had only one to go loses this game, then the doubling cube comes back into the action, even though s/he is still only 1 game away from the win. The rationale for the rule can be illustrated in the following example: suppose the score is 15-14 in a 16 game tournament. The player on 15 games ought to have an advantage in the match. But if the doubling cube is in play the other player can double on the first move and turn that particular game into a "winner takes all". Possession of the doubling cube returns no advantage to the leading player, because further doubling is irrelevant to the outcome of the match. This would be quite unfair.

Children of 6+ can play backgammon, preferably the easier version, without the doubling cube. And there are easier versions of the game that are more suitable for children of 4-5.The blocking game - backgammon without the doubling cube, without the "hitting and entering" part (a point with one checker is considered "closed") and without the regular setup. Instead, the checkers are placed off the board, and the players enter them and move them around the board according to the roll of the dice. To block the opponent, a player can add his checker to a pile of 2 or more checkers of the opponent on a point - once one player's checker tops the pile, the second player is blocked and unable to move.Blocking express - same as the blocking game, except that every double (2's, 3's etc) entitles the thrower to play the double and the higher doubles.Blast Off - same as backgammon but with no cube, no hitting, no entering. the board setup is slightly different (two more checkers on the midpoint instead of on the 1-point). The first player who finishes bearing off - wins the game.
