The top of each fence post is a square pyramid . The side length of the base of the fence top is 10.1 centimeters . The height of the fence is 8.868 centimeters. What is the volume of the post top

Respuesta :

Answer:

301.54 cubic centimeters.

Step-by-step explanation:

Given:

The top of each fence post is a square pyramid.

The side length of the base of the fence top is 10.1 cm.

The height of the fence is 8.868 cm.

Question asked:

What is the volume of the post top ?

Solution:

First of all we will find base area of the fence then volume of post top (square pyramid)

Side length = 10.1 cm

As we know:

[tex]Area\ of\ square=(Side)^{2}[/tex]

                         [tex]=(10.1)^{2} =102.01\ cm^{2}[/tex]

Now

[tex]Volume\ of\ square\ pyramid=\frac{1}{3} \times base\ area\times height[/tex]

                                            [tex]=\frac{1}{3} \times102.01\times8.868=\frac{904.62}{3} =301.54\ cm^{3}[/tex]

Thus, volume of the post top is 301.54 cubic centimeters.
