Answer:

h=94.87

Step-by-step explanation:

1. Volume of pyramid formula:

v=\frac{1}{3}*a^{2}*h

a=b*h Base Edge * Height of Pyramid

2. We have variables:

V = 480, Base Edge = 10, Height of Base = 16 (Inch)

3. Plug into formula + Rearrange:

\frac{3V}{h} =(b*h)^{2} [b^{2} *h^{2} ]

\frac{3V*b^{2} }{h} =h^{2}

h^{2}=\frac{3*480*10^{2} }{16}

h=\sqrt{9000}

h≅94.868
