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.
The answer is 35000 cubic feet.
Using the digits of 1345678, there are 210 three digit numbers in which no digit is repeated.
Do the calculations, then round to one decimal digit, since the least precise of the numbers involved has one decimal digit.

They tell you what level of precision you can expect from measurements that are made using that instrument.
Answer: 152.1
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 help communicate the precision of a measurement. They indicate the level of certainty in the measured value and help prevent misleading conclusions. Using the correct number of significant figures ensures accuracy and consistency in scientific data analysis.

79.0 has three significant figures - as trailing zeros after a decimal point are not usually written, to have been written the zero must have significance. Thus 9174.48 needs to be rounded to 3 significant figures, which is done by using the 4th digit to round the 3rd: the 4th digit is 4, so the number rounds down to 9170
Yes, I could.-- If the sequence is significant, then there are 720 different possibilities,and I can't list all of them here.-- But if the sequence is not significant, then there is only one possible6-digit group ("combination") using the digits 1, 2, 3, 4, 8, and 9.
