find the volume of the triangular prism to the nearest whole unit

OpenStudy (anonymous):

terenzreignz (terenzreignz):

Okay, so what you have to do is get the area of the triangle up front, can you do that?

terenzreignz (terenzreignz):

Once you find that area, multiply it to the length of this triangular prism... and you'll have the volume

OpenStudy (anonymous):

no i have no clue how to find the area:(

terenzreignz (terenzreignz):

Formula for the area of a triangle is \[\Large \frac12\times base \times height\]

terenzreignz (terenzreignz):

The triangle up front has height 2 and a base of length 12...

terenzreignz (terenzreignz):

So the area of that triangle is...?

OpenStudy (anonymous):

i already know the answer its 216ft^3 but i need the formula on the volume

terenzreignz (terenzreignz):

Yes... okay, if you must have the formula for volume... then here it is :) For a triangular prism, the volume is given by \[\Large \frac12 \times base\times height \times length\]

terenzreignz (terenzreignz):

base here being 12 height being 2 and length being 18

OpenStudy (anonymous):

alright thanks:) a lot:)

terenzreignz (terenzreignz):

No problem :)

OpenStudy (anonymous):

do you know the formula for a cone?

OpenStudy (anonymous):

OpenStudy (anonymous):

i know the formula i just cant figure out how to simplify it 1/3(Area of Base)(height) = 1/3 pi r2 h

terenzreignz (terenzreignz):

Yeah, volume of a cone is given by \[\Large V = \frac13 \times \pi \times r^2\times h\]

OpenStudy (anonymous):

ok thanks that much more simple

terenzreignz (terenzreignz):

Just key in... what's your radius?

OpenStudy (anonymous):

im not sure yet hold on

OpenStudy (anonymous):

6in

OpenStudy (anonymous):

i think i got it

terenzreignz (terenzreignz):

Okay :)

terenzreignz (terenzreignz):

Just remember pi is just 3.1416 (approx) and your height is 11

OpenStudy (anonymous):

lol sorry but do you know the formula for a pyramid?
