Answer:

92400m

Step-by-step explanation:

<em>Find the volume of the two rectangles.</em>

Volume of a rectangle: length*width*height

The first, larger rectangle: 64*60*28=107520m

The second, smaller rectangle: 18*30*28=15120m

<em>Subtract the two rectangles' volumes for the building's total volume.</em>

107520-15120=92400m

{(2,9), (2,8), (-3,7), (-3,6)} is what type of relation?
Fittoniya [83]

OK, the relation. (2,9), (2,8), (-3,7) (-3,6)

Since 2 maps to two values, as does -3,  this relation is not a function.

~~~~~~~~~~~~~

By the way these points, in this slightly different order, 

(2,9), (2,8), (-3,7) (-3,6)

are the vertices of a parallelogram.
