My home is on the 6th floor Each staircase is 3 meters long How many meters do I have to walk home f

Every time I get home from the first floor, I have to walk 15 meters.

Solution: I know that my family lives on the 6th floor, and each staircase is 3 meters long, so the distance I walk from the 1st floor to the 6th floor The number of floors from the 1st floor to the 6th floor The length of each staircase.

15 meters. A: I have to walk 15 meters from the 1st floor to the 6th floor.

The meaning of multiplication

There are many problems in life that need to add the same number in a row, if you still take the method of calculating the result of addition in turn, when the number of consecutive additions is large, such calculations will be very redundant.

In order to facilitate and fast calculation, the form of continuous addition is converted into the form of multiplication of two numbers, and the operation result can be obtained quickly, and the meaning of multiplication can be realized in combination with continuous addition. Further understanding of multiplication, familiarity with the formula of multiplication, understanding the meaning of the numbers in the formula, and correctly reading and writing multiplication equations.

Use multiplication in practical problems to analyze the problem, solve the problem, list the equations and calculation steps, use multiplication to solve the practical problem, and calculate the predetermined result.

Every time I get home from the first floor, I have to walk 15 meters.

Analysis: My home is on the 6th floor, and each staircase is 3 meters long, so I have to walk 6-1=5 flights of stairs every time I go home.

3 meters per floor, home 5x3 = 15 meters.

If this is really an elementary school question, the answer is this.

Isn't there anyone wondering if each staircase is only 3 meters long? Isn't that perpendicular to every floor?

If there were two flights of stairs on each floor, each 3 meters long, I would think it would be more reliable.

Every time I get home from the first floor, I have to walk 15 meters.

Analysis of Seep Bianxiang:

My home is on the 6th floor, and each staircase is 3 meters long, but I have to walk 6-1=5 flights of stairs every time I go home.

3 meters per floor, home 5x3 = 15 meters.

Summary. Pro, 12 meters.

This building has 7 floors, my family lives on the 5th floor, each floor is 3 meters high, how many meters does the elevator have to go from the 1st floor to the 5th floor.

Pro, 12 meters.

This building has 7 floors, my family lives on the 5th floor, each floor is 3 meters high, how many meters does the elevator have to go from the 1st floor to the 5th floor. Please give a solution process, ideas, thank you.

Pro, the first floor is not on the first floor, directly on the first floor.

How to explain to the child, thank you.

From the meaning of the question, there are 5-1 = 4 (floors) 3 4 = 12 (meters) Answer: The elevator has to walk 12 meters from the 1st floor to the 5th floor. This is a multiplication problem in the table, which is solved according to the quantitative relationship in the question. Judging by the title, the elevator went from the 1st floor to the 5th floor, and actually walked the distance of the (5-1) floor; Next, according to the meaning of "3 meters high on each floor" and the meaning of multiplication, find the number of meters to be walked.

1-2 This is a 3 meter.

2-3 This is one.

3-4 This is one.

4-5 This is one.

5 When you get to the door, you don't have to go up.

So a total of 4 3 meters walked, which is 12 meters, so easy to understand.

Reincarnation 3 5 = 15 meters, 5 flights of stairs to climb on the 6th floor.

Willow waves and warblers nuclear honor limbs.

Dear Sesame will be happy to answer for you.

You are the driving force we carry with us.

The first floor to the third floor is 6 meters, so the first floor is 2 meters, so the 10th floor is 20 meters high.

Since there are two flights of stairs from the first floor to the third floor, each staircase is 20 2 = 10 steps, and from the first floor to the sixth floor, it is five flights of stairs.

So take 5x10=50 stairs.

20÷(3-1)×6=60

There are 60 steps from the first floor to the sixth floor.

3x5=15 (m).

A: Xiao Gang needs to walk 15 meters to walk home from the first floor.

3*(6-1)=15m.

Xiao Gang. The family lives on the 6th floor and needs to climb 5 flights of stairs.
