Vol= 0.000729

Answer 2

Question: Find the volume of a cube of side 9 cm in cubic metres.

Solution:

$volume \: of \: cube \: = (side)^{3} \\ = (9 \: cm) ^{3} \\ = 729 \: cm ^{3} \\ also \: 1 \: cm \: = 10 ^{ - 2} m \\ volume \: = 729 \: cm ^{3} \\ = 729 \times (10 ^{ - 2} m) ^{3} \\ = 729 \times 10 ^{ - 6} m ^{3}$
