Question

aflati aria si volumul cubului cu lungimea laturei de
3 intreg 1/9 cm

Answer 1

l=3intreg1/9=28/9=3,(1)
Sa se afle Aria si Volumul
Rezolvare:
Vcubului=m³
Vcubului=3,(1)³
Vcubului=30,112cm³
Aria=6*m²
Aria=6*3,(1)²
Aria=6*9,679
Aria=58,074cm²

Answer 2

[tex] A_{cub}=6l^2=6* (3 \frac{1}{9}cm )^2=6* \frac{28}{9} cm^{2} = \frac{56}{3} cm^2 \\ V_{cub}= l^{3}= (3 \frac{1}{9}cm )^3= (\frac{28}{9}cm)^3 = \frac{21952}{729} cm^3[/tex]
