<h2>Answer:</h2>

The early atmosphere on Earth was mostly carbon dioxide and <u>poisonous</u>.

<h2>Explanation:</h2>

The earth's atmosphere in pre-historic times was carbon dioxide with little or no oxygen. Other noxious gases included ammonia, methane, water vapor, and neon. Scientists believe that the atmosphere of the earth during its formation resembled the current atmosphere on Mars and Venus.

Much change was caused by the photosynthesis process from plants which consumed carbon dioxide and released oxygen. Furthermore, carbon dioxide dissolved in the ocean. The water vapor condensed and formed the oceans due to temperature reductions.

Find the volume of a pyramid with a square base, where the area of the base is 19.6 ft^2 and the height of the pyramid is 11.6 f
xenn [34]

Answer:

volume ≈ 75.8 ft³(nearest tenth of a cubic foot)

Explanation:

A square base pyramid has the base of the pyramid as a square. The lateral faces are triangular. The volume of a square base pyramid is the product of the base area and the height of the pyramid divided by 3.   Mathematically, it is expressed below

The volume of a square base pyramid = 1/3Bh

where

B = base area

h = height of pyramid

B = 19. 6 ft²

h = 11. 6 ft

volume = 1/3 × B × h

volume = 1/3 × 19.6 × 11.6

volume = 227.36/3

volume = 75.7866666667

volume ≈ 75.8 ft³(nearest tenth of a cubic foot)
