Wzory:
[tex]V = a \cdot b \cdot c\\Pc = 2(ab+ac+bc)[/tex]
Dane:
[tex]a = 4dm = 40cm\\b = 3cm\\c = 2m = 200cm[/tex]
Liczymy objętość (V):
[tex]V = a \cdot b \cdot c\\V = 40cm \cdot 3cm \cdot 200cm = \boxed{24000cm^3}[/tex]
Liczymy pole całkowite (Pc):
[tex]Pc = 2(ab+ac+bc)\\Pc = 2(40cm \cdot 3cm + 40cm \cdot 200cm + 3cm \cdot 200cm) = 2 \cdot 8720cm = \boxed{17440cm^2}[/tex]
