Find the volume of the prism.<br> 9km 8km 6km
HACTEHA [7]

The correct answer is option B which is the volume of the prism is 216 km³.

<h3>What is the volume of the prism?</h3>

A prism is a three-dimensional solid with a triangular base called a triangular prism. The volume of the triangular prism is equal to the product of the area of the base and the height of the prism.

The volume of the prism will be calculated by using the formula below:-

V  =  Area of the base   x   Height

Since the base is a right-angle triangle so we will calculate the area of the right-angle triangle.

V  =  Area of the triangle  x  Height

V  =  ( 1/2 ) x 8 x 6 x ( 9 )

V  =  216 km²

Therefore the correct answer is option B which is the volume of the prism is 216 km³.

Answer:

c

Step-by-step explanation:

The formula for the volume of a square pyramid is a^{2} \frac{h}{3}. a is your base edge and the h is your height. In this case it would be 5^{2} \frac{7}{3}. when you wokr it out it would be 58.333, or 58 which is c.

also you would do 5 x 5 then you would multiply it by 7/3.
