Determine the volume of the cone

The volume of a square pyramid is:

Where

a = base dimension

From the attachment, the base dimension of the square pyramid is 2r.

So:

The volume becomes;

To calculate the volume of the cone, we simply multiply the given ratio and the volume of the prism.

So, we have:

Open bracket;

Cancel out 4

The above can be written as:

So, we have:

or

t = 3

step-by-step explanation:

put t = 3 in this expression :

(3²-1)(3²-2)(3² - 3)(3² - 4) = 8×7×6×5 = 56×30 = 1680
