A=L*l= 3,88*2,56= 9,9328 m²
4cm=0,04m
A unei dale=(0,04)²= 0,0016m²
9,9328:0,0016=6208 dale sunt necesare
4cm=0,04m
A unei dale=(0,04)²= 0,0016m²
9,9328:0,0016=6208 dale sunt necesare
A=L*l
A=3.88*2.56
A=9.9328m^2 - aria podelei
4cm=4/100m=0.04m
A=0.04*0.04
A=0.0016m^2 - aria unei dale
9.9328/0.0016=6208
6208 dale sunt necesare
