Answer:

306.9

Step-by-step explanation:

The equation for the volume of a right triangular prism is to <u>(this is for the base of the triangle)</u> multiply the base by the height and then by 1/2. This will determine the area. Then take the height of the whole prism and multiply that to the base's area. That will give you the volume. So in your case: 9 times 6.2 times 1/2 equals 27.9. Then multiply 27.9 by 11 to get 306.9. I hope this helps!

What is the volume of the regular pyramid?

ad-work [718]

Answer:

Step-by-step explanation:

The volume of the regular pyramid is $V=\dfrac{1}{3}A_{base}H.$

The base of given pyramid is regular hexagon with side 12 cm. The are of this hexagon consistsof area of 6 equilateral triangles and is equal to

$A_{base}=6\cdot \dfrac{1}{2}\cdot 12\cdot 10.4=374.4\ cm^2.$

Hence, the volume of the pyramid is

$V=\dfrac{1}{3}\cdot 374.4\cdot 36=4,492.8\ cm^3.$
