Please kak jawab nomer 3,4,5 kurang itu saja

3) suhu Fahrenheit = (9/4) x R + 3°
= 9/4 x 72° + 32° = 9 (18°) + 32° = 162° + 32° = 194° F

Suhu Celsius = 5/4 x R = 5/4 x 72° = 5 x 18° = 90°

4) x = 360° - (140° + 140° + 30°) = 360° - 310° = 50°

5) panjang kawat = 5 m = 500 cm
Panjang kerangka kubus (seharusnya balok)
= 4 x( p + l + t)
= 4 x (40 + 30 + 30)
= 4 x (100)
= 400 cm
Sisi kawat = 500 cm - 400 cm = 100 cm = 1 m
