Step-by-step explanation:
- TSA (total surface area) of cuboid= 2(lw+wh+hl)
and the problem said one small cube with 1m width that means it also has 1m length and height
so lets count the cubes for the height, length and width
- Height contains 4 cubes (4m)
- Length contains 4 cubes also (4m)
- Width contains 2 cubes (2m)
Now lets put the givens we got from the figure in the formula of TSA
2*(4*2+4*2+4*4)=64
