Answer:
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

Answer:
The complete area of the given figure is
Step-by-step explanation:
Total number of rows = 2
Squares in each row = b
So, the total number of squares in 2 rows = 2 x ( Squares in 1 row ) = 2 x b
Also, side length of 1 square = b cm
As we know, AREA OF SQUARE = SIDE x SIDE
So here, area of 1 square = Side x side = b cm x b cm =
⇒ The area of total (2b) squares = 2 b x ( Area of 1 square)
Hence, the complete area of the given figure is
