4.1 is rational. A rational number is a number that can be expressed as a ratio of two integers. 4.1 = 41/10. Decimal numbers that have an infinitely repeating sequence (e.g., 0.1111111111... = 1/9), or a limited number of digits (e.g., 0.123457 = 123457/1000000), are all rational.
The formula for volume is L*W*H. Since multiplication is commutative, it doesn't matter what order the numbers are given in, the same answer results. If you turn a box on its side, its volume doesn't change as a result of that, even though which measure is the "height" will change.

4.1 is rational.
no, it does not matter which is which. The formula for volume is L x W x H. It does not matter which order they are listed, as the multiplication works out the same either way.
Hope this helps.

4.1 is rational because it can be represented as one integer divided by another. in this case, 41/10
it does not matter which side is which because of commutativity

Rational,
and no, not really,
the formula is l x w x h,
so as long as you measure them correctly,
you're good.
