Question

Minta tolong dong jawab...

Answer 1

Volume kubus semula = 10 * 10 * 10
= 1.000 cm³

Faktornya = 1.000 / 8
= 125

Volume kubus sekarang = 125 * 27
= 3.375 cm³

Panjang rusuk setelahnya = ∛3.375
= 15 cm

==========

luas sisi ABCD = PL
luas sisi ABFE = PT
luas sisi BCGF = LT

PL = 56
P = 56 / L

PT = 32
56/L * T = 32
T = 32 / (56/L)
T = 32L / 56

LT = 28
32L / 56 * L = 28
32L² / 56 = 28
32L² = 1.568
L² = 1.568 / 32
L² = 49
L = √49
L = 7 cm

LT = 28
7T = 28
T = 28 / 7
T = 4 cm

PT = 32
4P = 32
P = 32 / 4
P = 8 cm

volume = 7 * 4 * 8
= 224 cm³

Answer 2

V kubus = 10 × 10 10 = 1000 , 1000 ÷ 8 = 125 , V kubus 2 = 27 × 125 = 3.375 , = v. Kubus = S . S . S = 3.375 = 15 . 15. 15 , pnjng rusuk = b. 15 cm
