What is the product of the number 1000 and the measurement of 003 57m expressed in the correct member of significant digits?

To calculate the product of 1000 and 003 57 m (which is 3.57 m), we first note that 3.57 has three significant figures. Multiplying 1000 by 3.57 gives 3570. However, since 1000 has only one significant figure, the final result should also be expressed with one significant figure, resulting in 4000 m (rounded to the nearest thousand).
