If two pyramids are similar and the ratio between the lengths of their edges is 4: 9, what is the ratio of their volumes?

Ration between the volumes = 64:729

Step-by-step explanation:

If two pyramids are similar and ratio between the lengths of their edges is 4:9

Then we have to tell the ration between their volumes.

Since volume of pyramid

Let length and width of pyramid one are l and w.

So volume of one pyramid

Now by the ratio of 4:9, edges of the second pyramid will be

Therefore volume of second pyramid  

Now ratio of volumes of both the pyramids =

Answer is 64:729 will be the ratio of their volumes.
