6. diagonal=√s^2+s^2 50 =√2s^2 50 = s√2 s = 25√2 L p = 6s^2 = 6(25√2)^2 = 6 x 2500 = 15000 cm^2 [D] 7. p = 7 cm l = 3 cm t = 5 cm Lp = (2 x p x l)+(2 x p x t)+(2 x l x t) = ( 2 x 7 x 3)+(2 x 7 x 5)+(2 x 3 x 5) = 42 + 70 + 30 = 142 cm^2 [D] 8. tinggi alas = √10^2 - 6^2 = √64 = 8 cm V = Luas Alas x t = (12x8)/2 x 15 = 48 x 15 = 720 cm^3 [C]
diagonal=√s^2+s^2
50 =√2s^2
50 = s√2
s = 25√2
L p = 6s^2
= 6(25√2)^2
= 6 x 2500
= 15000 cm^2 [D]
7.
p = 7 cm
l = 3 cm
t = 5 cm
Lp = (2 x p x l)+(2 x p x t)+(2 x l x t)
= ( 2 x 7 x 3)+(2 x 7 x 5)+(2 x 3 x 5)
= 42 + 70 + 30
= 142 cm^2 [D]
8.
tinggi alas
= √10^2 - 6^2
= √64
= 8 cm
V = Luas Alas x t
= (12x8)/2 x 15
= 48 x 15
= 720 cm^3 [C]
