d2
Explanation
Total surface area of a cube = s sq. unit
Diagonal of a cube = d unit
Let one side of cube x unit.
\therefore Total surface area (s) = 6x2 sq unit
Diagonal (d)=\sqrt{3 x} unit
∴ s = 2d2
∴ \frac{s}{2}= d2
Question
If total surface area of a cube is s sq. unit and the length of the diagonal is d unit, then the relation between s and d is (a) s = 6 d2 (b) 3s = 7d (c) s3 = d2 (d) d2 =\frac{s}{2}

The depth of a cuboidal pond with length of 20 m and breadth of 18.5 m is 3.2 m, let us write by calculating the time required to irrigate whole water of the pond with a pump having the capacity to irrigate 160 kilo lit water per hour. If that quantity of water is poured on a paddy field with a ridge having the length of 59.2 m and breadth of 40 m, then what is the depth of water in that land – let us write by calculating it.
