Answer:

55.4 in³

Step-by-step explanation:

The formula for the volume of a pyramid can be found:

V = $\frac{1}{3}Bh$ , 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 = $\frac{1}{2}bh$ = $\frac{1}{2}(5.7)(6.2)=17.67in^{2}$

Next, multiply the area of the base by the height of the pyramid:

17.67 x 9.4 = 166.098 ÷ 3 ≈ 55.4 in³
