Question

Cum se face aria si volumul unui cuboid 6/2/2?

Answer 1

Aria totala =aria fetelor=2*(6*2+6*2+2*2)=2*28=56
Volum =L*l*H=6*2*2=24

Answer 2

aflam aria unei fete mari ( sunt 4 )
a = L x l
a = 6 x 2
a = 12 m patrati
aria unei fete mici ( sunt 2)
a = l xl
a = 2 x 2
a = 4 m patrati
aria totala
4 x 12 + 2 x 4 = 48 + 8 = 56 m patrati

am folosit o unitate de masura aleatorie

volumul = L x l x h = 6 x 2 x 2= 12 x 2=24 m cubi
