Odpowiedź :
a)
a = 0,4 dm = 4 cm
b = 6 cm
c = 2 m = 200 cm
V = 4 * 6 * 200 = 4800 cm³
P = 2 * (4 * 6 + 6 * 200 + 4 * 200)
P = 2 * (24 + 1200 + 800)
P = 2 * 2024 = 4048 cm²
b)
a = 3 cm
b = 7 cm
c = 6 cm
V = 3 * 7 * 6 = 126 cm³
P = 2 * (3 * 7 + 7 * 6 + 3 * 6)
P = 2 * (21 + 42 + 18)
P = 2 * 81 = 162 cm²
