First find the area of this equilateral triangle |dw:1432088619509:dw| http://www.mathopenref.com/triangleequilateralarea.html

OpenStudy (anonymous):

43.3

jimthompson5910 (jim_thompson5910):

correct

jimthompson5910 (jim_thompson5910):

then multiply that by the prism's height or depth (29)

jimthompson5910 (jim_thompson5910):

Volume of prism = (area of base)*(height of prism)

OpenStudy (anonymous):

i did 43.4*29

OpenStudy (anonymous):

1,255.7 *

OpenStudy (anonymous):

is that the final answer??

jimthompson5910 (jim_thompson5910):

www.mathportal.org/calculators/plane-geometry-calculators/equilateral-triangle-calculator.php?val1=10&rb1=A&ch1=expl the area of the triangle is \[\Large 25\sqrt{3} \approx 43.30127\] (see the link above) 43.30127*29 = 1,255.73683 is the approx volume of the prism then you round that to the nearest tenth

OpenStudy (anonymous):

so I was correct lol

jimthompson5910 (jim_thompson5910):
