The length of the rectangular parallelepiped is 18 cm, the height is 15 cm, and the volume is 3240 cm3. Find the width of this box.

To solve this problem, we use the formula for finding the volume of a parallelepiped from the known values of the two sides and height: V = a * b * h, where V is the volume of the parallelepiped, a is the length of the parallelepiped, b is the width of the parallelepiped and h is the height of the parallelepiped, we derive the inverse formula: b = V / a * h. Now we substitute the known values that are given according to the conditions of the problem and calculate the width of the parallelepiped. Solution: 1) b = 3240/15 * 18. b = 3240/270. b = 12 centimeters wide. Answer: the width of the parallelepiped = 12 centimeters.
