Question

If S be surface area of V be the volume of cuboid of dimensions a,b and c then 1 / V is equal to

Answer 1

then .. dimensions is also half ...

1/2a

1/2b


1/2c

Answer 2

Given dimensions of cuboid are a, b and c.
Therefore, volume of cuboid, V = abc → (1)
Surface area of cuboid, S = 2(ab + bc + ca) → (2)

Now divide (2) with (1), we get
