Answer:
Volume of the pyramid = 16m³ or 16 cubic meters.
Explanation:
The equation for the volume of a pyramid is:
![V=(b*h)/(3)](https://img.qammunity.org/2020/formulas/mathematics/college/piljjm2en1rt7j9ylqfl5utty9q7wygqkh.png)
where b = area of base and h = height.
In this case, the base is a square with a side length of 4m.
Area of the square base = (4m)² = b = 16m²
h = 3m
Insert b and a into the volume of a pyramid equation.
![V=(3m*16m)/(3)](https://img.qammunity.org/2020/formulas/mathematics/college/sqv0r3zb0hc2i7x4alm5z5fasdt4m3n95f.png)
= 16m³
Volume of the pyramid = 16m³ or 16 cubic meters.
