Forging a cubic iron block with a side length of 6 decimeters into a cuboid part with a bottom area of 15 square decimeter. What is the height of this part?

List the volumes of two cubes and cuboids respectively to make them equal, and list the equations.

The main path of a cube is a cube with long sides.

The volume of a cuboid is the bottom area multiplied by the height.

Cubic of 6 = 15* part height.

Then the height of the part = 6/ 15 cube.

Part height = 14.4 decimeter.
