Lp = 6 x s
294 = 6 x s
s = 294 : 6
s = 49 cm

(diagonal ruang)²= s² + (diagonal sisi)²

misal diagonal ruang= c dan diagonal sisi= d

d² = s² + s² = 49² + 49² = 2401 + 2401 = 4802
d = √4802 = √(2401 x 2) = 49√2 cm

c² = s² + d² = 49² + (49√2)² = 7203
c = √7203 = √(2401 x 3) = 49√3 cm
jadi diagonal ruangnya adalah 49√3 cm
