What is the linear equation for this graph? (y=mx+b)

A rectangular prism has a volume of 750 cubic millimeters. Its length is 15
umka2103 [35]

Answer: 5 milimeters.

Step-by-step explanation:

The formula for calculate the volume of a rectangular prism is:

V=lwh

Where "V"  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:

V=750mm^3\\l=15mm\\w=10mm

Substitutute these values into the formula and solve for the the height "h":

750mm^3=(15mm)(10mm)h\\\\h=\frac{750mm}{(15mm)(10mm)}\\\\h=5mm
