Find the surface area of the closed rectangular box shown

6cm, 5cm, 3cm
S.A.= (LW)+2(HL)+2(HW)

I did: (5x6)+2(5x3)+2(6x3)=96 am I correct?

6cm, 5cm, 3cm
This formula for the surface area is for an open box with length L and width W:
S.A.(open)= (LW)+2(HL)+2(HW)

For a closed box, it would be:
S.A.(closed)= 2(LW+HL+HW)

You would do: 2(5x6)+2(5x3)+2(6x3)=?
