Answer:
Use the formula V = (1/3)Bh, where V is the volume, B is the area of the base, and h is the height.
Explanation:
Find the area of the base triangle using the formula
A = (1/2)bh where A is the area, b is the base of the triangle, and h is the height of the triangle
For this example, the area of base B is..
A = (1/2)(5)(12)
A = 30 m²
The volume of the pyramid is...
V = (1/3)(30)(10)
V = 100 m³
