1. A rectangular water storage tank with a volume of 100,000 liters, its bottom area is 40 square meters, and its height is (m.

100000l=100000dm³=100m³100/40=

2. The length, height and width are 4 meters. Rice. The area of the cuboid pool is (10m).

4*3, cut a cube with an edge length of 1 decimeter into two equal cuboids, the volume of each cuboid is (, and the surface area is (4dm).

The above is wrong!

The upper bottom is extended by 6cm and becomes a parallelogram, indicating that the original trapezoidal lower bottom is 9cm long, and the area has increased by 6 square centimeters, indicating that the original trapezoid is 2cm high

So the original trapezoidal area is.

Rice. 15 cubic meters.

cubic meters, 8 square meters.

2.10 square meters.

3.Cubic decimeter 4 square decimeter.

square meters = 4000 square decimeters = 4000 liters.

100000/4000=25 dm=

1. Sixteen thirds.

3 25 1 25.

4 1/8 3 13.

and times the problem.

If the decimal point of the number A is shifted to the right by one place, it is the same as the number B, and B is 10 times that of A =

B = 10

The number B is 10 times that of A, so it is 10 11 of the sum

Stats Statistics. Polyline

Scalloped meters.

Fifth grade, it's been a long timeThe raw data of statistics can be plotted both as () tables and () as graphs.

To represent the temperature change in a certain area, it is better to use a (lined) statistical chart.

In a bar chart, 20 people are represented by a centimeter-long bar, and 100 people are represented by a (centimeter-long bar).

The 9 numbers are added together, and their average is 54, and after removing one of the numbers, the average of the remaining 8 numbers is 45, and the number removed is (126).

To represent the distribution of China's land area, a (fan-shaped) chart should be used.

1. Columnar fan-shaped.

2. Broken line. 5, fan-shaped 6,

1.The sum of the subtracted, subtracted, and differential is equal to 68, and the subtracted number is (34) subtracted number = subtraction + difference = 68 2 = 34

2.A three-digit number that is divisible at the same time, and the number in the hundred place is 9 greater than the number in the ten place, it is (900).

3.(tonnes = 3 tonnes 15 kg hectares = (37,050) square meters.)

24 years old, baby rhinoceros 13

To understand the meaning of the topic, the age difference between the little rhinoceros and his mother is a constant number, when the little rhinoceros is 2 years old, his mother is his current age, and there is an age difference between them, he grows to his mother's current age, which is the second age difference between him and his mother, and his mother grows to 35 years old, which is the third age difference, so there is a total of three age differences between 35 and 2 years old, that is, the age difference is: (35-2) 3=11 years old.

Mom this year: 35-11=24 years old.

Baby rhinoceros this year: 24-11 = 13 years old.

Draw a line segment diagram.

It was found that there was a 3 age difference between 35 and 2 years old.

The age difference between the baby rhinoceros and his mother is a constant number, when the baby rhinoceros is 2 years old, his mother is his current age, there is an age difference between them, he grows to his mother's current age, that is, the second age difference between him and his mother, his mother grows to 35 years old, which is the third age difference, so there is a total of three age differences between 35 and 2 years old, that is, the age difference is: (35-2) 3=11 years (35-2) 3=11 years

11 + 2 + 11 = 24 years old.

Draw a line diagram first.

It was found that there was a 3 age difference between 35 and 2 years old.

11 + 2 + 11 = 24 years old.

Mom is 24 years old.

If you don't understand, ask.

The mother rhinoceros is (24) years old this year, and the baby rhinoceros is 13 years old You can verify.

Mom 24, rhinoceros 13, who came up with this question, my mother was born at the age of 11. . .

Uh, it's wrong, I'm sorry.

The baby rhinoceros is 13 years old and the rhinoceros mother is 24 years old.
