Question

um cubo tem 10 rais de 3 aresta calcule a medida de sua diagonal

Answer 1

DF=raiz(a²+a²)
DF=raiz(((10√3)²+(10√3)²)
df=raiz(100*9+100*9)
df= raiz(900+900)
df=raiz(1800)
df= 42,42cm
dc²=a²+df²
dc=raiz[(10√3)²+42,42²]
dc= raiz[100*9+1800]
dc= raiz(2700)
cd=51,96cm

a dagonal do cobo com 10√3 de aresta é: 51,96cm
