A regular square pyramid has base edges of length 16 and its lateral faces are inclined 30­° to the base of the pyramid. What is
Helga [31]

Answer:

1) h=\frac{8\sqrt{3}}{3}\ units

2) V=\frac{2,048\sqrt{3}}{9}\ units^3

Step-by-step explanation:

Part 1) Find the height of the pyramid

we know that

tan(30^o)=\frac{h}{(b/2)}

where

h is the height of the pyramid

b is the length side of the square base

we have

tan(30^o)=\frac{\sqrt{3}}{3}

b=16\ units

substitute

\frac{\sqrt{3}}{3}=\frac{h}{(16/2)}

\frac{\sqrt{3}}{3}=\frac{h}{8}

h=\frac{8\sqrt{3}}{3}\ units

Part 2) Find the volume of the pyramid

we know that

The volume of the pyramid is equal to

V=\frac{1}{3} Bh

where

B is the area of the square base

h is the height of the pyramid

we have

B=(16^2)=256\ units^2

h=\frac{8\sqrt{3}}{3}\ units

substitute

V=\frac{1}{3} (256)(\frac{8\sqrt{3}}{3})

V=\frac{2,048\sqrt{3}}{9}\ units^3
