Question

А=6 дм, в=15 дм, с=2дмнайти:сумму длин всех рёбер

Answer 1

Всё прибавить выйдет 23

Answer 2

Все цифры прибавить,то есть 6+15+2=23 дм =230 см

Answer 3

To find the sum of the lengths of all edges (sides) of the solid figure, we need to sum up the lengths of all the edges.

Let's assume the solid figure is a rectangular prism with sides A, B, and C. A rectangular prism has 12 edges, and each edge has a length. The formula to find the sum of the lengths of all edges is:

Sum of edge lengths = 4A + 4B + 4C

Given the values: A = 6 dm (decimeters) B = 15 dm (decimeters) C = 2 dm (decimeters)

Now, plug in the values:

Sum of edge lengths = 4(6) + 4(15) + 4(2) = 24 + 60 + 8 = 92 dm

So, the sum of the lengths of all edges of the rectangular prism is 92 decimeters.
