How do I work out the area of a triangle prism as a surd? I've got the area of the triangle as a surd 2√70 and the length (which is 46cm). Thanks. Last edited by skipjack; February 28th, 2017 at 08:00 AM.

$46 \cdot 2\sqrt{70} = 92\sqrt{70} \, cm^3$ You really need to work on your arithmetic with radicals... Last edited by skipjack; February 28th, 2017 at 08:01 AM.
