Calculate the volume of a regular octahedron whose edges are all 10 cm (do not use the formula to find the volume)

V≈471.4cm³

Step-by-step explanation:

V =

V= 471.4

Here we have given that the all edges if octahedron are 10 cm. We need to find the volume of regular octahedron.

As we know that the formula of volume of octahedron is :

Substituting all the given values in the formula to find the volume of regular octahedron :

Hence, the volume of regular octahedron is 471.404 cm³.

3-4

step-by-step explanation:

the answer is 3-4 because both 45 and 60 has a multiple of 15.

45/3=15

60/4=15

therefore the odds against selecting a red is 4-3

answer is 144
