h=2√3 - wyliczanie ze wzoru na wysokosc trojkata
boku
h=a√3/2
a√3/2 =2√3 | * 2
a√3=4√3 | : √ 3
a = 4
Pp= a√3/4
pp 4√3/4
Pp=√3
V=√3/3 * 7 - noi teraz liczymy objętość
V=7√3/3
to tyle :) mam nadzieje ze sie odwdzięczysz xd hehe
h = 2√3
V = ?
h = (a√3)/2 |•2
2h = a√3 |:√3
a = (2h)/√3
a = (2h√3)/3
a = (2•2√3•√3)/3
a = 4cm
P = (a²√3)/4
P = (4²√3)/4
P = (16√3)/4
P = 4√3cm²
V = PH
V = 4√3 • 7
V = 28√3cm³
