Szczegółowe wyjaśnienie:
1
[tex]p.pow = 6 {a}^{2} = 6 \times {11}^{2} = 726cm^{2} [/tex]
Prawdziwe
2
[tex]p.boczne = 3 \times a \times h = 3 \times 3.5 \times 5 = 52.5 {cm}^{2} = 0.525 {dm}^{2} [/tex]
Fałsz
3
[tex]p.szescian = 6 {a}^{2} = 6 \times 3 \times 3 = 54{cm}^{2}[/tex]
[tex]p.prostopad = 2 \times 3 \times 2 + 2 \times 4 \times 2 +3 \times 4 \times 2 = 52{cm}^{2}[/tex]
Fałsz
4
[tex] a = \frac{60}{12} = 5cm[/tex]
[tex]p.pow = 6 {a}^{2} = 6 \times {5}^{2} = 150 {cm}^{2} [/tex]
Prawda
Powinno być ok :)
