Suppose each edge of the cube shown in Figure 10 is 5.00 inches long. Find the measure of the angle formed by diagonals CF and *CH.* Round your answer to the nearest tenth of a degree.

Figure 10

To determine

**To find:**

The measure of the angle formed by diagonals CF and CH rounding the answer to the nearest tenth of a degree.

**Given information:**

In the above given figure each edge of the cube is 5 inches long.

**Concept Used:**

**Calculation:**

Suppose A, B, C, D, E, F, G and H are the vertex of the cube whose each edge is 5 inches long.

Now first we will find the diagonal CH of the cube using Pythagorean Theorem as follows;

Similarly, to find the diagonal CF of the cube using Pythago
