The volume of a rectangular pyramid is
V = (1/3) A*h
where
A = the area of the rectangular base
h = the height
The two pyramids are congruent in volume.
The volume of one pyramid is
(1/3)*(2*7.5)*(6) = 11
The volume of the composite figure is 2*11 = 22
Answer: 22
Answer:
d= -5
Step-by-step explanation:
The slope of a line is found by finding the ratio of change is y values to change is x values

The points on the line have coordinates at: (-1,7) (-3,d)
where ;

Applying the formula with values as;

The value of d = -5
The coordinates of the points (-1,7) (-3,-5)
