Question

A metal cuboid of measures 16 cm x 11 cm x 10 cm was melted
to make coins. How many coins were made, if the thickness and
diameter of each coin was 2 mm and 2 cm respectively ?
(nt = 3.14)​

Answer 1

Answer:

Step-by-step explanation:

For the metallic cuboid,

l= 16cm , b= 11cm , h= 10cm

For cylindrical coin,

Diameter=2cm , Thickness= 2mm = 0.2cm

radius = diameter/2 = 2/2 = 1

Let the number of coins made be N

N × Volume of coin = Volume of cuboid

N × pie r^2h = l × b × h

N× 22/7 × 1× 1×2/10 = 16×11×10

N = 16×11×10×10×7/22×2

N = 2800

Number of coins made are 2800

Answer 2

Answer:

2800 COINS...........
