Question 11 Find out how many coins should be stacked to match the height of the Statue of Unity. Assume each coin is 1 mm thick. Height of statue of unity = 180 m To find number of coins to be stacked, we need to convert this height into mm Thus, Height of statue of unity = 180 m = 180 × 1 m = 180 × 100 cm = 180 × 100 × 1 cm = 180 × 100 × 10 mm = 1,80,000 mm Now, Number of coins to be stacked = (𝐻𝑒𝑖𝑔ℎ𝑡 𝑜𝑓 𝑠𝑡𝑎𝑡𝑢𝑒 𝑜𝑓 𝑢𝑛𝑖𝑡𝑦)/(𝑇ℎ𝑖𝑐𝑘𝑛𝑒𝑠𝑠 𝑜𝑓 𝑐𝑜𝑖𝑛) = 1,80,000/1 = 1,80,000 coins
