Triangle=1/2 rectangle
so therefor a rectangle with similar legnth widht and height has 2 times the vollume of this prism
find volume and half it
V=LWH
V=16*12*8*
V=1536
half it
V=768
volume=768 cm^3
If it takes 3 hours at 30 km per hour than that 90 km total distance and at 45 km per hour that would mean that distance would be travelled in 2 hours. So the answer should be 2 hours
The missing side length would be 3 because if you multiply 3*15*3=135 you get the volume.
It has one X-intercept. Graph it on Desmos and you can see the line, and then it becomes obvious it is one x-intercept.
