Answer:
The volume of the given pyramid is 340.8 cubic feet.
Explanation:
The volume of an object is a consideration of the dimensions of the object with respect to 3 dimensions.
volume of a pyramid = 
x base area x height
But,
base area = length x width
= 12 x 12
= 144 square feet
So that,
volume of the pyramid = x 144 x 7.1
= x 1022.4
= 340.8
The volume of the given pyramid is 340.8 cubic feet.

B. An atom is a solid sphere
Explanation:
The idea that the atom was a solid sphere paved back to the first atomic model in the <em>19th century</em> theorized by <em>John Dalton</em>. According to him, an atom is <u>intact and hard and cannot be broken down or divided</u>.
However, many scientists continued to research and it was found that <em>the atom was not actually a solid sphere.</em> It was made up of<em> protons (positively-charged), electrons (negatively-charged) and neutrons (neutrally-charged). </em>This invalidated Dalton's solid sphere model.
The biosphere is all living things on earth
