V = 2,406 cm

Explanation:

The formula in the picture

Answer 2

well, from the picture above, we can see it has a height of 24.4 cm and a 17.2x17.2 cm² base.

`\textit{volume of a pyramid}\\\\ V=\cfrac{Bh}{3} ~~ \begin{cases} B=\stackrel{base's}{area}\\ h=height\\[-0.5em] \hrulefill\\ h=24.4\\ B=\stackrel{17.2* 17.2}{295.84} \end{cases}\implies V=\cfrac{(295.84)(24.4)}{3}\implies V\approx 2406.17~cm^3`
