It was a life changing event. Around 66 million years ago, at the end of the Cretaceous period, an asteroid struck Earth, triggering a mass extinction that wiped out the dinosaurs and around 75% of all species.
Dinosaurs roamed the Earth in the Mesozoic Era, which is divided into the Triassic, Jurassic, and Cretaceous periods. They first arose during the Triassic period about 245 million years ago. Dinosaurs first appeared in the Middle Triassic and became the dominant terrestrial vertebrate in the Late Triassic or Early Jurassic, occupying this position for about 150 to 135 million years until their demise at the end of the Cretaceous. This era is popularly known as the "Age of Reptiles" and for good reason: reptiles, and particularly dinosaurs, were the dominant terrestrial vertebrate animals at the time. The PT extinction was the most severe in Earth's history, and was likely driven by intense volcanic eruptions and associated rapid climate change. This extinction decimated many early groups of reptiles and amphibians, and may have created environmental space for dinosaurs and other new groups to evolve.

Hi there!
The formula for the volume of a rectangular prism is length x width x height. Using this formula, we can plug in the numbers given, multiply them together, and find the volume of the prism.
WORK:
V = 6 x 1 x 3
V = 6 x 3
V = 18cm^3
Hope this helps!! :)
If there's anything else that I can help you with, please let me know!
The correct answer is C. humans
