My answer: 1,025.3 yd ^3. Is that correct?

OpenStudy (jack1):

volume = area of the base x the length

OpenStudy (anonymous):

length or height?

OpenStudy (jack1):

so it's a triangular prism, so whats the area of the triangle?

OpenStudy (jack1):

length / height / tallness / whatever

OpenStudy (jack1):

so: area of an equilateral triangle = ??? @Lollygirl217

OpenStudy (anonymous):

1,255.7yd ^3

OpenStudy (anonymous):

hmm??

OpenStudy (jack1):

yep, done

OpenStudy (anonymous):

I hope you are not just saying that

OpenStudy (jack1):

nope, done

OpenStudy (anonymous):

area of an equilateral triangle with side s is A = sqrt(3)/4 * s^2

OpenStudy (anonymous):

sourwing...I am correct?

OpenStudy (jack1):

yeah, she just posted the volume tho

OpenStudy (anonymous):

thats all there needs to be

OpenStudy (anonymous):

ah, triciall is here.

OpenStudy (anonymous):

How bout it?

OpenStudy (anonymous):

whatever the value of sqrt(3)/4 * (10)^2 * 29 is

OpenStudy (triciaal):

the volume of a prism is the base area * height

OpenStudy (anonymous):

Is my answer correct, yes or no

OpenStudy (triciaal):

to the nearest tenth means to 1 decimal place

OpenStudy (triciaal):

give me a min let me open etc

OpenStudy (anonymous):

k

OpenStudy (triciaal):

one approach what is the height of the triangle? times the base of 29* 10

OpenStudy (anonymous):

OOOH. It's 2,511.5yd^3?
