The volume of a Pyramid

Given a pyramid of base area A and height H, the volume is calculated as:


V=(A\cdot H)/(3)

The base of this pyramid is a right triangle, with a hypotenuse of c=19.3 mm and one leg of a=16.8 mm. The other leg can be calculated by using the Pythagora's Theorem:


c^2=a^2+b^2

Solving for b:


b^{}=\sqrt[]{c^2-a^2}=\sqrt[]{19.3^2-16.8^2}=9.5\operatorname{mm}

The area of the base is the semi-product of the legs:


A=(16.8\cdot9.5)/(2)=79.8\operatorname{mm}^2

Now the volume of the pyramid:


V=\frac{79.8\operatorname{mm}\cdot12\operatorname{mm}}{3}=319.2\operatorname{mm}^3

The volume of the figure is 319.2 cubic millimeters
