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

7.the answe ris x+3 since it can be factored out of the 5x+15 tingie (second )
8. fourth or $\frac{x^{2}+4x}{4}$
9. fourth or $\frac{2y+6}{9y-7}$ times $\frac{3}{2}$
10. third or $\frac{(x+3)(x+8)}{(x-8)(x-8)}$
11. second or $\frac{x-5}{x-4}$
12. third or 11(x+7)=60
