Identify the number given: 1.059 qt.
Recall that significant figures are the digits in a number that carry meaning contributing to its precision, including all nonzero digits, zeros between significant digits, and trailing zeros in a decimal number.
Count the digits in 1.059: the digits are 1, 0, 5, and 9.
Since all these digits are significant (the zero is between nonzero digits), the number 1.059 has 4 significant figures.
Therefore, the number of significant figures in 1.059 qt. is 4.
