Best ResponseYou've already chosen the best response.1So area of triangle = sqrt(3) s/2 * s/2 =sqrt(3) s/4

Best ResponseYou've already chosen the best response.1what do i do for the volume then? @mathmate

mathmate

Best ResponseYou've already chosen the best response.1The volume is obtained by multiplying the area of the base (Ab) and the height. You can use the calculator for that.

Best ResponseYou've already chosen the best response.1I have 526.54 if you use more accurate numbers for sqrt(3), such as 1.7321 (instead of just 1.73). Good job.
