Question

Длина прямоугольного параллеле- Sock пипеда равна 5 дкі; ширина на 8 м меньше длины, а высота составляет 5/7 ширины. Найди объём и площадь поверхности этого прямоугольного параллелепипеда. СРОЧНО!​

Answer 1

Дано :

Длина -  5дм = 50 см

Ширина - 50-8=42 см

Высота - 42*5/7  =30

Решение :

1) V = ABC = 30 * 42 * 50 = 63 000

2) S (поверхности) = 2(ab + bc + ac)

3) S = 2(50 * 42 + 42 * 30 + 50 * 30) = 2(2100 + 1260 + 1500) = 9720

Ответ : 9720

Calculation of Volume and Surface Area of a Rectangular Parallelepiped

To find the volume and surface area of a rectangular parallelepiped, we need to know the length, width, and height of the parallelepiped. Let's calculate them based on the given information.

Given: - Length of the rectangular parallelepiped = 5 units - Width of the rectangular parallelepiped = Length - 8 units - Height of the rectangular parallelepiped = (5/7) * Width

Calculation of Width:

The width of the rectangular parallelepiped is given as 8 units less than the length. Therefore, we can calculate the width as follows:

Width = Length - 8

Substituting the given length value, we have:

Width = 5 - 8 = -3 units

However, a negative width is not possible in this context. Please provide the correct values for the length, width, and height of the rectangular parallelepiped so that we can proceed with the calculations.
