Answer:
0.422 L
Step-by-step explanation:
A little-used fact is that a <em>liter</em> is a <em>cubic decimeter</em>. The dimensions of your cube are ...
edge length = 75 mm = 75/1000 m
Since a decimeter is 1/10 of a meter, we want the denominator to be 10. Moving the numerator and denominator decimal points 2 places to the left, we get ...
edge length = 0.75/10 m = 0.75 dm
Then the volume of the cube is ...
V = (0.75 dm)^3 = 0.422 dm^3 = 0.422 L
