is 10,500 cubic centimeters. It has a
length of 15 centimeters and a width of
85 centimeters. What is its height?

Respuesta :

Answer:

Its height is 24.71 centimeters.

Step-by-step explanation:

Given:

The volume of a rectangular pyramid  is 10,500 cubic centimeters.

It has a  length of 15 centimeters and a width of  85 centimeters.

Now, to find the height.

Let the height be [tex]h.[/tex]

Volume of rectangular pyramid  = 10,500 cubic centimeters.

Length (l) = 15 centimeters.

Width (w) = 85 centimeters.

Now, to get the height by putting formula:

[tex]Volume=\frac{l\times w\times h}{3}[/tex]

[tex]10500=\frac{15\times 85\times h}{3}[/tex]

[tex]10500=\frac{1275h}{3}[/tex]

Multiplying both sides by 3 we get:

[tex]31500=1275h[/tex]

Dividing both sides by 1275 we get:

[tex]24.71 =h\\\\h=24.71\ centimeters.[/tex]

Therefore, its height is 24.71 centimeters.
