what's the volume of a rectangular prism if it has a length of 20 inches and a width of 12 inches and a height of 6 inches​

1,440

Step-by-step explanation:

we know: volume = h · d · w

given: length = 20 inches,  width= 12 inches, height = 6 inches.

20 x 12 x 6 = 1,440

( multiply l x w x h to find the volume)

the answer is; biodiversity resulting from few ancestors

adaptive radiation occurs when a population is subjected to a large natural environment with spatial ecological variations. the parts of the population in the different ecologies begin to adapt to their local environments. due to non-random mating across the large populations, this causes the different populations from the large population to speciate within their local environments. they, therefore, diverge to different species sharing a common ancestor.
