Question

Tolong dong nomor 48 pakek caraya... makasih

Answer 1

V = P x L x T
750 = 3a x 2a x a
750 = 6a³
a³ = 125
a = 5

P = 3a = 3(5) = 15 cm
L = 2a = 2(5) = 10 cm
T = a = 5 cm

Maka;
Lp = ( 2 x P x L ) + ( 2 x P x T ) + ( 2 x L x T )
Lp = ( 2 x 15 x 10 ) + ( 2 x 15 x 5 ) + ( 2 x 10 x 5)
Lp = 300 + 150 + 100
Lp = 550 cm²

Jadi, jawabannya C. 550 cm²
