Question

In Indus Valley Civilisation (about 300 B.C.), the bricks used for construction work were having dimensions in the ratio
A. 1:3:4
B. 4:2:1
C. 4:4:1
D. 4:3:2

Answer 1

Hint- The Indus Valley Culture (IVC), often denoted by its major city Harappa, spanned almost two millennia from 3200 to 1300 BC. Its tradition reaches back to approx. 6800 BC: a 4000-year long expansion of villages and towns, of trading activity, and of technological advancements culminates between 2600 and 1900 BC in the built-up of large brick-built cities.

Complete step by step solution:
In Indus Valley Civilisation the dimensions of the bricks were in the ratio
length:breadth:thickness=4:2:1.
Later, the ratio changed in Harappan Civilisation.
Basic structure of bricks used In Indus Valley Civilisation (about 300 B.C.)

Bricks having structure similar to the cuboid.
And as we know,
Cuboid has six faces; thus, we say bricks having also 6 faces as shown in figure.
Volume of brick (Cuboid) = l$ \times $h$ \times $w
Area of the base = l$ \times $w
Area of the total surface =2(lw+lh+hw)
The Indus Valley is traversed by the Indus and Saraswathi Rivers, covering 1.6 million square kilometers. As a result of many archaeological ‘finds,’ this one was accidental, in addition to unusual: the find was an entire civilization.
Therefore, Option (B) is the correct answer.

Note- Today, the Harappa site is a UNESCO World Heritage Centre. The area was the domain of India at the time of the discovery; Therefore, it was part of the British Raj. during the initial discovery period. while, after India was partitioned, this terrain was split between Pakistan and India.
