Answer 1

Answer:

$64m^{2}$

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

1. Height contains 4 cubes (4m)
2. Length contains 4 cubes also (4m)
3. 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
