Possible solutions - using your rules are:- 11,13,17,31,33,37,71,73 &77
By using front end estimation, the numbers that you start of with have only one significant digit. It is, therefore, nonsense to have an answer with loads of significant digits.
Using the digits of 1345678, there are 210 three digit numbers in which no digit is repeated.
The answer is 35000 cubic feet.
Do the calculations, then round to one decimal digit, since the least precise of the numbers involved has one decimal digit.

William Thomson, also known as Lord Kelvin, is credited with introducing the concept of significant figures in the late 19th century. He recognized the importance of indicating the precision of measurements by using digits that were known with certainty along with one uncertain digit.
Significant figures play a crucial role in dimensional analysis by indicating the precision of measurements. When performing calculations, it is important to consider the number of significant figures in each measurement to ensure the accuracy of the final result. Using the correct number of significant figures helps maintain the precision of the calculations and ensures that the final answer is reliable.

Significant figures are important because they indicate the degree of accuracy - the minimum amount by which a quantity is distinguished to be different from a similar amount.The more significant figures the more accurate the data will be.
Unit prefixes in scientific measurements are significant because they allow for easier representation of very large or very small quantities. By using prefixes such as kilo, mega, milli, and micro, scientists can express measurements in a more concise and standardized way, making it easier to compare and understand data across different scales.
The answer is 35000 cubic feet.
