No, no lil one, you're going wrong.
- 1.a. Calculate the total surface area of the cube. 6(l^2) =144x6 =864sq.inch
- 1.b. Calculate the volume of the cube. l^3 =12x12x12 =1728cu.inch
Slove the rest by yourself
Remember:
- Surface area of cuboid is 2(lb+bh+hl), where l is length, b is breadth and h is height.
- Volume of cuboid is lbh, where l, b, h mean the same as in 1.
