Answer 2

Answer:

92400m

Step-by-step explanation:

Find the volume of the two rectangles.

Volume of a rectangle: length*width*height

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

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

Subtract the two rectangles' volumes for the building's total volume.

107520-15120=92400m
