Answer: 5 milimeters.
Step-by-step explanation:
The formula for calculate the volume of a rectangular prism is:
[tex]V=lwh[/tex]
Where "V" Â is the volume, "l" is the lenght, "w" is the width and "h" is the height.
You know that the volume, the lenght, and the width of this rectangular prism are:
[tex]V=750mm^3\\l=15mm\\w=10mm[/tex]
Substitutute these values into the formula and solve for the the height "h":
[tex]750mm^3=(15mm)(10mm)h\\\\h=\frac{750mm}{(15mm)(10mm)}\\\\h=5mm[/tex]
