The great Nature has intended us to earn our bread in the sweat of our brow. Every one, therefore, who idles away a single minute becomes to that extent a burden upon his neighbours, and to do so is to commit a breach of the very first lesson of ahimsa. Ahimsa is nothing if not a well-balance, exquisite consideration for one's neighbour, and an idle man is wanting in that elementary consideration. (YI, 11-4-1929, p. 144-15)
Volume of each cube = 64 cm3
∴ Total volume of the two cubes = 2 × 64 cm3
= 128 cm3
Let the edge of each cube = x
∴ x3 = 64 = 43
∴ x = 4 cm
Now, Length of the resulting cuboid l = 2x cm
Breadth of the resulting cuboid b = x cm
Height of the resulting cuboid h = x cm
∴ Surface area of the cuboid = 2 (lb + bh + hl) = 2[(2x . x) + (x . x) + (x . 2x)]
= 2[(2 × 4 × 4) + (4 × 4) + (4 × 2 × 4)] cm2
= 2 [32 + 16 + 32] cm2 = 2[80] cm2 = 160 cm2.
