The length of the rectangular parallelepiped is 14cm, the width is 8cm and the height is 7cm.

The length of the rectangular parallelepiped is 14cm, the width is 8cm and the height is 7cm. Find the height of the other rectangular parallelepiped, if its length is 28cm, width is 7cm, and the volume of the first parallelepiped.

Find the volume of the first parallelepiped. Let’s multiply its length, width and height:

V = 14 * 8 * 7 = 784 cm3

Now we multiply the length and width of the second parallelepiped:

28 * 7 = 196 cm2

To find the height of the second parallelepiped, divide the volume of the first parallelepiped by the product of the length and width of the second:

784: 196 = 4 cm height of the second parallelepiped.

Answer: the height of the second parallelepiped is 4 cm.
