cube problem 4:
A cube box has an edge length of 4.3 cm
a) calculate the volume
b) calculate the surface and the body diagonale
answer:
a) answer volume
V = el³
V = 4.3³
V = 79,51 cm³
A: The volume is 79,507 cm³.
b) answer surface and the body diagonale
face diagonale 1,2,3 = el * √2
face diagonale 1,2,3 = 4.3 * √2
face diagonale 1,2,3 = 6.08 cm
body diagonale = el * √3
body diagonale = 4.3 * √3
body diagonale = 7.45 cm
A: The face diagonale is 6.08 cm and the body diagonale is 7.45 cm.
