Answer:

The area of the base B is equal to $770\ cm^{2}$

The volume is equal to $10,087\ cm^{3}$

Step-by-step explanation:

I will proceed to resolve the problem indicated in the attached figure.

The figure shown a inverted rectangular pyramid

The base is a rectangle

The area of the base B is equal to

$B=(35)(22)=770\ cm^{2}$

To find how many cubic centimeters of titanium are needed to manufacture one tip, calculate the volume of the figure

<em>Find the volume of the inverted rectangular pyramid</em>

The volume of the pyramid is equal to

$V=\frac{1}{3}BH$

we have

$B=770\ cm^{2}$

$H=39.3\ cm$

substitute

$V=\frac{1}{3}(770)(39.3)=10,087\ cm^{3}$
