Answer:
Surface area:
[tex]2(12\times 6) + 2(6 \times 8) + 2(8 \times 12)[/tex]
[tex]2((12\times 6) + (6 \times 8) + (8 \times 12)[/tex]
Volume :
[tex](12 \times 6 \times 8)[/tex]
Neither:
[tex]8(12 \times 6)[/tex]
[tex]2(12 \times 6 \times 8)[/tex]
[tex]12+6+8[/tex]
Step-by-step explanation:
Surface area of the cuboid:
The Surface area of the cuboid = 2(lb) +2(bh) +2(hl)
Where
l =length of the cuboid
b = Breadth of the cuboid
h = height of the cuboid
So ,
The surface area will be
SA = [tex]2(12\times 6) + 2(6 \times 8) + 2(8 \times 12)[/tex]
SA = [tex]2((12\times 6) + (6 \times 8) + (8 \times 12))[/tex]
SA =[tex]2(72+48+98)[/tex]
SA = [tex]2(216)[/tex]
SA = 432
Volumes of the cuboid:
[tex]Volume = length \times breadth \times height[/tex]
Volume = [tex](12 \times 6 \times 8)[/tex]
volume = 576
