Quiz
- t = 458 cm
- l = 25 cm
- p = 369 cm
⬇️ Volume
v = p × l × t
v = 458 × 25 × 369
v = 4.225.050 cm³
⬇️ Luas permukaan
lp = 2 × ((p × l) + (p × t) + (l × t))
lp = 2 × ((369 × 25) + (369 × 458) + (25 × 458))
lp = 2 × ((9.225) + (169.002) + (11.450))
lp = 2 × 189.677
lp = 379.354 cm²
Jawaban:
➥ Diketahui
P = 369 cm
l = 25 cm
t = 458 cm
➥ Ditanya : volume dan luas permukaan?
==============================
Volume = p × l × t
= 369 CM × 25 cm × 458 cm
= 4.225.050 cm³
Luas permukaan
= 2 × ( p×l ) + ( p×t ) + ( l×t )
= 2 × (369×25)+ (369×458) + ( 25 × 458)
= 2 × 9225+169.002 + 11.450
= 2 × 189,677
= 379.354

✎Keterangan
Volume balok = p × l × t
luas permukaan = 2 × ( p × l ) + ( p × t ) + ( l× t)
