The most straightforward method will be to convert each of the inch measurements into meters:
There are 39.37 inches per meter, so one inch is 0.0254 meters.
15 inches x 0.0254 inches/meter = 0.3810 meters
23 inches x 0.0254 inches/meter = 0.5842 meters
10 inches x 0.0254 inches/meter = 0.2540 meters
Now you have a box .381 m x .5842 m x .254 m.
Multiplying that out:
.381 x .5842 x .254 m x m x m = 0.0565 m³
Alternatively, you could multiply 15 in x 23 in x 10 in to get 3,450 in³, then multiply in³ by 1.639e-05 m³/in³ to convert to m³:
3,450 in³ x 1.639e-05 m³/in³ = 0.0564 m³
The 1.639e-05 in³/m³ conversion factor is really just 0.0254 in/m x 0.0254 in/m x 0.0254 in/m multiplied out in advance.
In my opinion, doing it the first way is more logical, but the second method is faster.
