Answer:
0.001875 m^3
Explanation:
Well the difference between meter and cm is 100 and because you are changing the cm to meter you will divide by 100 so you will have 0.25 m x 0.05 m x 0.15 m.
Now for the volume of the cube is L x W x H which will be 0.25 m x 0.05 m x 0.15 m and you will have 0.001875 m^3 this will be the volume
Hope that helps :)
