How many triangles can be constructed with sides measuring 14cm, 8 cm, and 5 cm?

1 answer:

8 0

Answer: B

Explanation: No triangle can be formed.

According to the triangle inequality theorem, the sum of any two sides must be greater or equal than the length of the third side.

Here, the sides are 14 cm, 8 cm, and 5 cm.
14cm + 8 cm = 22 cm > 5cm (theorem followed)
14 cm + 5 cm = 19 cm > 8 cm (theorem followed)
8 cm + 5 cm = 13 cm < 14 cm (theorem not followed)

Since, the triangle inequality theorem is not followed, Hence, no triangle can be formed.

The volume of a cube is 216 cubic inches. What is the length of each side of the cube?

Zielflug [23.3K]

Answer:

6 inch

Step-by-step explanation:

If you remember the concept of how to find volume of cube then its pretty easy.

You find it by multiplying the length of one side by itself 3 times.

In this case we have to do opposite so we have to just find the cube root of 216 which is 6.
