Answer:
55.4 in³
Step-by-step explanation:
The formula for the volume of a pyramid can be found:
V = , where B = area of the base and h = height of the pyramid
Since the base is a triangle, we need to use the formula for the area of a triangle:
A = =
Next, multiply the area of the base by the height of the pyramid:
17.67 x 9.4 = 166.098 ÷ 3 ≈ 55.4 in³
