ДАЮ ВСЕ СВОИ БАЛЛЫ СРОЧНО НАДО! 7 КЛАСС Как изменить ребро куба чтобы его объем уменьшился в m¹² раз!??? ДАМ ЛУЧШИЙ ОТВЕТ ПЕРВОМУ КТО ОТВЕТИТ

Answer 1

Ответ:

Длину ребра уменьшить в m⁴ раз

Объяснение:

V=a³ объем куба

V₁ - первоначальный объем

V₂ - объем после уменьшения в m¹² раз

a₁ - первоначальная длина ребра

a₂ - уменьшенная длина ребра

V₂=a₂³

V₂=a₁³/m¹²

a₂³=a₁³/m¹²

a₂=∛(a₁³/m¹²)

a₂=∛(a₁³)/∛(m¹²)

a₂=a₁/m⁴

a₂/a₁=m⁴

Answer 2

To decrease the volume of a cube by m¹² times, you would need to change the length of its edges. Let's break down the steps to achieve this:

1. Calculate the initial volume of the cube: The volume of a cube is given by the formula V = s³, where s is the length of one of its edges.

2. Determine the desired volume: To decrease the volume by m¹² times, you need to calculate the desired volume by dividing the initial volume by m¹².

3. Find the new length of the edges: To find the new length of the edges, you can take the cube root of the desired volume. This is because the volume formula for a cube is V = s³, so by taking the cube root, you can find the new length of the edges.

4. Calculate the ratio of the new length to the initial length: Divide the new length of the edges by the initial length to find the ratio.

5. Apply the ratio to each edge: Multiply each edge length of the cube by the ratio calculated in step 4 to obtain the new lengths of the edges.

By following these steps, you can change the length of the edges of a cube to decrease its volume by m¹² times.

Please note that without specific values for the initial length of the cube's edges or the desired reduction factor (m), it is not possible to provide exact numerical values for the new lengths of the edges. However, the steps outlined above should help you calculate the new lengths based on your specific values.
