The length of the rectangular parallelepiped is 18 cm, the height is 15 cm, and the volume is 3240 cm ^ 3.

The length of the rectangular parallelepiped is 18 cm, the height is 15 cm, and the volume is 3240 cm ^ 3. Find the width of the given box.

To find the width of the parallelepiped, you need to write down the formula for the volume of the parallelepiped and derive the formula for the width from it.

So, V = a * b * c, where:

a = 18 cm, parallelepiped length;

b = 15 cm, parallelepiped height;

V = 3240 cm ^ 3, the volume of a parallelepiped.

Find with =? cm, the width of the parallelepiped.

c = V / a * b

c = 3240/18 * 15 = 3240/270 = 12 cm.

Answer: the width of the parallelepiped is 12 cm.
