- 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)

Answer:
Step-by-step explanation:
Given that

Right side has values as
53, 53+77, 53+2(77),+....
We have to find one which is a perfect square.
We have from this series 361 is 19 square
Thus 
Next is 
and so on.
(0.14×675×25)÷(2×12)=98.44
675+98.44=773.44
773.44÷24=32.23
