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

What is the fastest way to calculate 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9?
Oral calculation, 1 + 9,2 + 8,3 + 7,4 + 6 + 5 = 45
Cube, volume 511cm cubic, calculate the edge length
The edge length is ᦉ 179; √ 511, and the total edge length is 6 ᦉ 179; √ 511
If the side length of a cube is 1.5 times 10 to the second power cm, then the volume of the cube is
375 times the sixth power of 10
Measured from the inside, the cuboid box with the edge length of 1 decimeter has a volume () that can hold () liquid
Eight one cubic centimeter cubes can be made into cubes with a length of 2 cm, or cuboids with a length of 4 cm, a width of 2 cm, and a height of 1 cm. The volume of a chalk box is 5 cubic meters. A large coke bottle can hold 1.25 liters of coke. Xiaohong uses 5 liters of natural gas a month
The volume of a cube box with an edge length of 1 decimeter is (1 cubic decimeter) and can hold (1 liter) liquid. Eight one cubic centimeter cube wood blocks can be assembled into a cube with an edge length of 2 cm, It can also be put together into a cuboid which is 4cm in length, 2cm in width and 1cm in height (√). The volume of a chalk box is 5M3 (×). A large coke bottle can hold 1.25l of coke (√) Xiaohong uses 5L of natural gas in one month (√)
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
