Objętość
[tex]V = 7cm \times 6cm \times 12.5cm = \boxed{\underline{ 525 {cm}^{3} }}[/tex]
Pole podstawy
[tex]7cm \times 6cm = 42 {cm}^{2} [/tex]
Pole ścian bocznych
P1
[tex]7cm \times 12.5cm = 87.5 {cm}^{2} [/tex]
P2
[tex]6cm \times 12.5cm = 75 {cm}^{2} [/tex]
Pole całkowite
[tex]2 \times 42 {cm}^{2} + 2 \times 87.5 {cm}^{2} + 2 \times 75 {cm}^{2} = 84 {cm}^{2} + 175 {cm}^{2} + 150 {cm}^{2} = \boxed{\underline{409 {cm}^{2} }}[/tex]
