Question

Cara mengetahui luas permukaan prisma jika yg diketahui perbandingannya 3:2:1 dan volume balok 750cm kubik.. tolong dengan rumus

Answer 1

V = p X l X t
750 = 3x X 2x X 1x
750 = 6x^{3}
125 = x^{3}
5 = x
jd
p=3x = 3 X 5 = 15,
l = 2x = 2 X 5 = 10
t = x = 5
L= 2 (pl+pt+tl)
  = 2 (150+75+50)
  = 2 (275)
  =550
