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.
The answer is artificial reef. Its a man made underwater structure typically built to promote marine life areas with a generally features bottom to control erosion, block ship passage or improve surfing. Artificial reef improve marine life in a certain area and deprive a new location for fishermen to fish and which works to ease the pressure on natural reefs.

Answer:
Circumduction is a conical movement of a body part, such as a ball and socket joint or the eye.
According to geographical analysis, the volume of groundwater that flows over a given time per unit area through a body of rock or sediment is called the "<u>hydraulic head</u>."
This is because the hydraulic head is based upon the gradient of the water table, including the permeability of the rock or sediment and groundwater thickness.
Hydraulic head is calculated in the form of liquid surface elevation.
Hydraulic head is usually expressed in units of length.
Hence, in this case, it is concluded that the correct answer is "<u>hydraulic head</u>."
