Answer:
Option A. 392 cm³
Explanation:
Formula to get the volume of a pyramid is
![V=(1)/(3)(l)(w)(h)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/3rih85h4osjuasd3iadif9naigjxv4tmre.png)
Here l = length of the base
w = width of the base
h = height of the pyramid
From the figure attached
l = w = 14 cm
h = 6 cm
Therefore,
![V=(1)/(3)(14)(14)(6)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/49dtz29buiu8n11y1egk7clt3dza7wrt9a.png)
V = 14×14×2 = 392 cm³
Option A. 392 cm³ is the answer.
