Answer 1

Answer:

measure of parallelipiped=16cm

Major of height of a parallelepiped=10cm

breath of parity pad = b = 11 centimetres

thickness of coin that is height H is equal to two millimetre therefore 0.2 centimetre

diameter of coin equals to centimetre therefore radius of coin = 1 cm

from first condition parallelepiped cuboid mills in two coins

therefore number of coins to perform equals volume of cuboid upon volume of coin

= l×b×h/pir^2×H

=16×11×10/22/7×1×0.2

=16×11×10×7/22×1×0.2

=8×10×7×10/0.2×10

=8×10×7×10/2

=4×10×7×10

=40×70

=2800

therefore 2800 coins are form
