Objętość sześcianu jest równa 16. Pole powieszchni całkowitej tego szescianu wynosi?
V = a³
a³ = 16√2
a³ = 2⁴ * 2^(1/2)
a³ = 2^(4 + 1/2)
a³ = 2^(9/2)
a = ∛(2^(9/2)
P = 6 * a²
P = 6 * (∛(2^(9/2))²
P = 6 * [ (2^(9/2)] ^(1/3) }²
P = 6 * [ 2^(9/2 * 1/3) ]²
P = 6 * [ 2^(3/2)]²
P = 6 * 2^(3/2 * 2)
P = 6 * 2^3
P = 6 * 8
P = 48cm²
