Answer 1

Answer:

Coins are cylindrical in shape.

Height (h1) of cylindrical coins = 2 mm =

0.2 cm

Radius (r) of circular end of coins =

0.875 cm

Let n coins be melted to form the required cuboids

Volume of n coins = Volume of cuboids

n × π × r² × h1 = l × b × h

n × π × (0.875)² × 0.2 = 5.5 × 10 × 3.5

n = 5.5 ×10 ×3.5 ×7 /0.875 ×0.875 ×0.2×22

= 400

Hence,

The number of coins melted to form the given cuboid is 400.
