What is the volume of the triangular prism?
Height: 12mm
Base: 15mm
Width:7mm
1) 34mm cubed
2) 187mm cubed
3) 630mm cubed
4) 1,260mm cubed
I can 100% understand your analysis but would you mind explaining to me how in the world you did it. I just want to learn so that next time I can do it on my own and maybe even teach someone else? I would appreciate it!
v = Bh
you know how to figure B -- it's just the area of the triangle, so ...
I so sorry but I don't get it....
well, you haven't said which two dimensions constitute the triangular base. If the triangle has base=15 and height=12, then its area is 90. Then the volume is 90*7 = 630
I'm thinking that I have the numbers here wrong but could you just tell me what I need to do in a way that is not confusing
The ans is 630 mm cubed because 12*15/2=90*width or 7=630.
and ur welcome
just as the volume of a rectangular brick is length*width*height, it is also base*height, with the base having area B=length*width, so v = Bh
A triangular prism also has volume Bh, where B is the area of the triangular base.
try googling prisms and volumes for more discussions. Whenever you are having trouble with whole ideas, and not just specific problems, google is the best place to start. Whatever is troubling you has been treated before.
I am in connexus too. I got C. I hope this helped
To calculate the volume of a triangular prism, you need to multiply the base area by the height.
The base of the triangular prism is a triangle, so first find the area of the triangle using the following formula:
Area = (base * width) / 2
In this case, the base of the triangle is 15mm, and the width is 7mm. So, the area of the triangle is:
Area = (15 * 7) / 2 = 105 / 2 = 52.5mm^2
Next, multiply the base area by the height of the prism to find the volume:
Volume = base area * height
Volume = 52.5mm^2 * 12mm
Volume = 630mm^3
Therefore, the volume of the triangular prism is 630mm^3. So the correct answer is option 3) 630mm cubed.
