Q. Genapin poin

Jawaban:

A. Luas Permukaan Kubus

  • 6 × r²
  • 6 × 16²
  • 6 × 16 × 16
  • 96 × 16
  • 1.536 cm²

B. Volume Kubus

  • r³
  • 16³
  • 16 × 16 × 16
  • 256 × 16
  • 4.096 cm³

Luas permukaan

Lp = 6 times {r}^{2}

Lp = 6 times (16 times 16)

Lp = 6 times 256

Lp = 1.536 : : cm

Volume

V = r times r times r

V = 16 times 16 times 16

V = 256 times 16

V = 4.096 : : {cm}^{3}
