Question

Tolong kerjakan no 4&5 ya pakai caranya trims :)

Answer 1

4.
p = 6a
l = 5a
t = 4a

LP = 2(p × l) + 2(l × t) + 2(p × t)
33.300 = 2(6a × 5a) + 2(5a × 4a) + 2(6a + 4a)
33.300 = 2(30a²) + 2(20a²) + 2(24a²)
33.300 = 60a² + 40a² + 48a²
33.300 = 148a²
     225 = a²
         a = 15

p = 6a
   = 6(15)
   = 90 cm

l = 5a
  = 5(15)
  = 75 cm

t = 4a
  = 4(15)
  = 60 cm

5.
p = 2a
l = 3a
t = 4a

V = p × l × t
9.000 = 2a × 3a × 4a
9.000 = 24a³
375 = a³
a = 5∛3

p = 2a
   = 2(5∛3)
   = 10∛3

l = 3a 
  = 3(5∛3)
  = 15∛3

t = 4a
  = 4(5∛3)
  = 20∛3
