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.

I'm pretty sure the answer is C. 78%. (KEEP READING)
Because you move the decimal over to the right two times and get 70 add a percent to the end and get 70%. _
But since it is repeating it would be 77%
So if you are rounding it to the nearest number, to ones, then the answer is C. But if you are rounding to the tens then it would be D.
I personally would put C because you want the "nearest percent".

- 2T = - 1.4
T = -1.4—2 = 0.7 hours = 42 minutes
Time she spent jogging = 1.2-0.7 = 0.5 hours = 30 minutes

Against wind :2400 miles in 10 hours
With wind : 2400 miles in 8 hours
Speed of plane = x
Speed of wind = y
t=d/r
against the wind speed x-y mph
with the wind x=y mph
2400/(x-y)=10
2400 = 10x-10y
240 =x-y eq.1
2400/x+y=8
2400 = 8x+8y
300 = x+y eq 2
Add eq1 & eq 2 = 740 = 2x
X = 740/2 = 370 mph for plane
300 = 370 +y
Y = 370-300 = 70 mph wind speed
