Correct Answer : 28 inches
A wicket consists of three stumps, or stakes, each 28 inches (71.1 cm) high and of equal thickness (about 1.25 inches in diameter), stuck into the ground and so spaced that the ball cannot pass between them. Two pieces of wood called bails, each 4.37 inches (11.1 cm) long, lie in grooves on the tops of the stumps. The bails do not extend beyond the stumps and do not project more than half an inch above them. The whole wicket is 9 inches (22.86 cm) in width. There are two of these wickets, which a batsman defends and a bowler attacks, and they are approximately in the centre of the ground, facing one another at each end of the pitch.
