How to use a simple calculation method
1×2÷3×4÷5×6÷7×8÷9
=(1×2×4×8×6÷3)÷(5×7×9)
=(2×4×8×2)÷(5×7×9)
=128÷315
=128/315
This method is relatively simple

How many liters of cuboid box with edge length of 5 decimeters
125
In a cuboid tin box, you can just put nine cubes with the edge length of 1 decimeter. The volume of the box is () if the thickness of the tin is ignored
So the volume of this box is ()
9 cubic decimeters, because it can place nine cubes with an edge length of 1 decimeter, then the sum of the volumes of the cubes is the volume of the tin box
In the cube box with the edge length of 1 decimeter, you can put several small cubes with the volume of 1 cubic centimeter
10 * 10 * 10 = 1000
The volume of a cube is 6400 cm, how long is its edge? The volume of a cube is 125 cubic meters, how long is its edge?
Cube volume = cube of edge length = 6400cm ^ 3
Then the edge length is 40 cm
The volume of a cube is 125 cubic meters
Then edge length = 5m
