Question

Which of the following is the largest volume?

1.2 x 105 cm3

1.2 x 102 m3

2.0 x 104 dm3

1.2 x 108 mm

Answer 1

1.2 x 102 m3

Answer 2

thanks thats what i figured out also!

Answer 3

Best way to do this is convert them all to the same volume unit, like liters
Then it would be:
\(\sf\large 1.2 x 10^5 cm3= 120 L \)
\(\sf\large 1.2 x 10^2 ~~m3 =120,000 L\)
\(\sf\large 2.0 x 10^4 dm3 =20,000 L\)
\(\sf\large 1.2 x 10^8 mm \) (millimeter) is not a volume unit so it can't be converted.
