Total volume is 720 cm^3.

Answer 2

Volume of the rectangular pyramid:

$v = \frac{lwh}{3}$

$v = \frac{9 \times 8 \times 9}{3}$

$v = 216 \: {cm}^{3}$

Volume of the rectangular prism:

$v = lwh$

$v = 8 \times 7 \times 9$

$v = 504 \: {cm}^{3}$

Total volume:

$v = 216 + 504$

$v = 720 \: {cm}^{3}$
