Answer
$V=705.18$ cm$^3$
Work Step by Step
Knowing the altitude of the pyramid, we can multiply it by the area of its base (acquired in part A), and one third in the equation:
Volume of a Pyramid $= \frac{1}{3}Bh$
Altitude:
$14.6$ cm
Area of base (B):
$144.9 $ cm$^2$
$V=\frac{1}{3}(144.9)(14.6)$
$V=705.18$ cm$^3$
