10√5=√25x²+36x²+64x²
10√5=√125x²
10√5=5x√5
10=5x
x=2
maka luas permukaan balok
2[(5.2x6.2)+(5.2x8.2)+(6.2x8.2)]=944 cm² (A)
Diaonal Ruang = √p²+l²+t²
10√5 = √(5a)²+(6a)²+(8a)²
√500 = √25a²+36a²+64a² kuadratkan kedua ruasnya
500 = 25a²+36a²+64a²
500 = 125a²
a² = 500/125
a = √4
= 2
Luas permukaan = 2(pxl+pxt+lxt)
= 2 (5ax6a+5ax8a+6ax8a)
= 2 (30a²+40a²+48a²)
= 2 x 118a²
= 236 x 2²
= 236 x 4
= 944 cm²
