Question

Показан прямоугольный паралелипитет 4дм, 8дм и 10дм вычислите сумму длин выделенных ребер

Answer 1

а = 4 дм - первое измерение

b = 8 дм - второе измерение

с = 10 дм - третье измерение

L = 4 · (a + b + c) = 4 · (4 + 8 + 10) = 4 · 22 = 88 дм - сумма длин всех рёбер

Ответ: 88 дм.

Answer 2

Calculation of the Sum of the Lengths of the Highlighted Edges in a Rectangular Parallelepiped

To calculate the sum of the lengths of the highlighted edges in a rectangular parallelepiped with dimensions of 4 dm, 8 dm, and 10 dm, we need to determine which edges are being referred to as "highlighted."

A rectangular parallelepiped has 12 edges. To identify the highlighted edges, we need more specific information or a visual representation. However, based on the given dimensions, we can make some assumptions.

Assuming that the highlighted edges refer to the edges that are parallel to the length, width, and height of the parallelepiped, we can calculate the sum of their lengths.

The length of the parallelepiped is 10 dm, the width is 8 dm, and the height is 4 dm.

The sum of the lengths of the highlighted edges can be calculated as follows:

- Sum of the lengths of the edges parallel to the length: 10 dm + 10 dm = 20 dm. - Sum of the lengths of the edges parallel to the width: 8 dm + 8 dm = 16 dm. - Sum of the lengths of the edges parallel to the height: 4 dm + 4 dm = 8 dm.

Therefore, the sum of the lengths of the highlighted edges in the rectangular parallelepiped is 20 dm + 16 dm + 8 dm = 44 dm.

Please note that without further clarification or a visual representation, it is difficult to determine the exact edges being referred to as "highlighted." The calculation provided assumes a specific interpretation based on the given dimensions.
