cube problem 2:
A cube has an edge length of 8.5 cm
a) calculate the surface area
b) calculate the volume
answer:
answer edge length:
A = 6 * el²
807.36 = 6 * el² / : 6
134.56 = el² / √
el = 11.6 cm
A: The edge length is 11.6 cm.
answer volume:
V = el³ (el * el * el)
V = 11.6³ (11.6 * 11.6 * 11.6)
V = 1 560.896 cm³
A: The volume is 1 560.896 cm³.
