Question

Длина прямоугольного параллелипипеда 14 см,ширина 8 см и высота 7 см.Найдите высоту другого параллелипипеда,если его длина 28 см,ширина 7 см,а объем равен объему первого параллелипипеда.НАПИШИТЕ ПО ДЕЙСТВИЯМ!

Answer 1

1) Находим (Объем) V 1-го параллелепипеда
14*8*7 = 784
2) Находим V 2-го параллелепипеда
784 : 28 : 7 
Или
784 : (28*7)
= 4
Ответ: Высота 2-го параллелепипеда

Answer 2

Calculating the Height of the Second Parallelepiped

To find the height of the second parallelepiped, we can use the formula for the volume of a parallelepiped, which is given by the product of its length, width, and height:

V = lwh

Given: - Length of the first parallelepiped (l1) = 14 cm - Width of the first parallelepiped (w1) = 8 cm - Height of the first parallelepiped (h1) = 7 cm - Volume of the first parallelepiped (V1) = l1 * w1 * h1

We are also given the dimensions of the second parallelepiped: - Length of the second parallelepiped (l2) = 28 cm - Width of the second parallelepiped (w2) = 7 cm - Volume of the second parallelepiped (V2) = V1 (since the volumes are equal)

Using the formula for the volume of a parallelepiped, we can rearrange it to solve for the height (h2) of the second parallelepiped:

h2 = V2 / (l2 * w2)

Substitute the values: h2 = V1 / (l2 * w2)

Now, let's calculate the height of the second parallelepiped using the given values.

Calculation

V1 = 14 * 8 * 7 = 784 cm³h2 = 784 / (28 * 7) = 784 / 196 = 4 cm

Answer

The height of the second parallelepiped is 4 cm.
