The cube container with the edge length of 6 decimeters is filled with water. Pour all the water in the container into a cuboid water tank. The water tank measures 6 decimeters long, 5 decimeters wide and 8.5 decimeters high from inside. At this time, what is the depth of water poured into the water tank? How many liters of water should I fill the tank?

(1) 6 × 6 × 6, = 36 × 6, = 216 (cubic decimeter); 216 ／ (6 × 5), = 216 ／ 30, = 7.2 (decimeter); (2) 6 × 5 × 8.5-216, = 30 × 8.5-216, = 255-216, = 39 (cubic decimeter); 39 cubic decimeter = 39 liters; a: the water depth into the water tank is 7.2 decimeters; to fill the water tank, 39 liters of water should be poured

A cube water tank is 4 decimeters long on each side. How deep is the water depth when pouring such a tank into another cuboid water tank which is 0.8 meters long and 25 cm wide?

8 M = 80 cm, 4 × 4 × 4 = 64 (cubic decimeter) = 64000 cubic cm, 64000 ^ (80 × 25) = 64000 ^ 2000 = 32 (CM) a: the water depth is 32 cm

Fill a square water tank with 40 cm long, and then pour the water into a cuboid 80 cm long and 20 cm wide. How much is the water

V=40×40×40=64000cm3
S=80×20=1600cm2
h=V/S
=64000/1600
=40cm
Water rise 40cm

(unit: cm) there is 1 long 15 wide 10 cuboid container with water and 5 high water. Put 4 eggs. Water rises by 2. There is a formula to calculate the volume of eggs. Thank you
One question is similar to this one. There is a 15 long, 10 wide rectangular container with 5 volumes of water in it. After putting 4 eggs, the water is 7 high, and the egg volume is calculated,

15*10*2/4=75

There are 42 fewer pear trees than apple trees in the orchard, and the number of apple trees is three times that of pear trees. How many apple trees and pear trees are there respectively? (lie equation)

Suppose there are x pear trees
3X-X=42
2X=42
X=21
There are 21 pear trees and 63 apple trees

Given a-3b = 2A + B-15 = 1, then the value of the algebraic formula a2-4ab + B2 + 3 is______ ．

A − 3B = 12a + B − 15 = 1, and a = 7b = 2, so the original formula is 72-4 × 7 × 2 + 22 + 3 = 0

1. The power of human beings unfolds in that moment. Struggle turns into the starting point of life in that moment. Everything turns into nothingness in that moment. I only know that victory is not far away. 2. When I look up, the finish line is already visible. Countless days and nights of hard work will be realized in the near future

Given that x + 4Y = 6Z, and 3x minus 4Y plus 2Z = 0, find the value of 2x + 3 / Z
Just today

From (1) x + 4Y = 6Z, we deduce x + 4y-6z = 0
(2)3x-4y+2z=0
If we want to add two formulas: 4x-4z = 0, then we deduce x = Z
Then: 2x + 3 / z = 2x + 3 / x = (2x ^ 2 + 3) / X
