Question

problema cub a=15cm aflati Ab Alat Atot V???​

Answer 1

Ab = a² = 15² = 225 cm²

Al = 4a² = 4×225 = 900 cm²

At = 6a² = 6×225 = 1350 cm²

V = a³ = 15³ = 3375 cm³

Answer 2

Trebuie sa stii formulele cubului:Al=4l^2;At=6l^2;V=l^3

Ab=15^2=225 cm^2

Al=4l^2=4x15^2=4x225=900cm^2

At=6l^2=6x15^2=6x225=1350cm^2

V=l^3=15^3=3375 cm^3

^2=la puterea a doua

^3=la puterea a treia
