Question

Geometria espacial ...

Answer 1

4) area total = abx6  e
ab= 96/6
ab = 16
ab = lxl
16 = lxl
l²=16
l=raiz(16)
l=4
volume = l³ = lxlxl = 4x4x4 = 64 m³
Volume = 64m³

DiagonaCubo² = Diagonal face² x aresta²
DF = lraiz(2)
DF = 4raiz(2)

DC²=(4raiz(2))² x l²
DC²=  (16x2)x16
DC = raiz(  512) 
DC=22,64m

5)
vc= 5x5x5 = 125cm3

VP=  4x5xX 
125 = 4x5xX
X= 125/20
X= 6,25 cm
