Julie has a box that is 12 by 12 by 4 find the surface area of the open box with

given:height(h)=12,width(w)=12,lenght(l)=4
formula:Total Surface Area = 2(Area(h*w)) + 2(Area(h*l)) + 2(Area(w*l))

i)if base(h*w)=12*12 then lid is open where h=12,w=12 and from above l=4
hence formula is:1(Area(h*w)) + 2(Area(h*l)) + 2(Area(w*l))
surface area of box = 1*(12*12) +2(12*4)+2*(12*4)
=144+96+96
=336 sq. units

ii)given base(h*w)=12*4 then one lid is open hence h=12,w=4 n from above l=12
formula is:1(Area(h*w)) + 2(Area(h*l)) + 2(Area(w*l))
1*(12*4)+2*(12*12)+2(12*4)
=48+288+96
= 432 sq. units

2nd box has more surface area
SA of 1st box => 12*4*4=192
SA of 2nd box => (12*2 + 4*2) * 12= 384

Since the base is 12 by 12 it will have one surface area . there is no lid
surface area of box = 1*(12*12) +2(12*4)+2*(12*4)=144+96+96=336 sq. units
Since the base is 12 by 4 it will have one surface area . there is no lid
base = 12 by 4
1*(12*4)+2*(12*12)+2(12*4)=48+288+96= 432 sq. units

Julie has a box that is 12 by 12 by 4. find the surface area of the open box with a base of that is 12 by 12 and open. find the surface area of the open box if the base was 12 by 4. Which box has more surface area.?
