Odpowiedź:
a = 4 cm
b = 5 cm
h = 8 cm
Pp - pole podstawy = a * b = 4 cm * 5 cm = 20 cm²
Pb -pole boczne = 2(a+b) * h = 2(4 + 5) cm * 8 cm = 2 * 9 cm * 8 cm =
= 144 cm²
Pc -pole całkowite = 2 * Pp + Pb= 2 *20 cm² + 144 cm² =
= 40 cm² +144 cm² = 184 cm²
V - objętość = Pp * h = 20 cm² * 8 cm = 160 cm²
