Question

A stack of 180 cards is placed next to a ruler in the height of stack is measured to be 3 fourths of an inch how thick is one card

Answer 1

Height of the stack = 3 fourth of an inch

=
`(3)/(4)` × (1 inch)

Height of 180 cards =
`(3)/(4)` × (1 inch)

Thickness of 1 card =
`(3)/(4)` ×
`(1)/(180)` × (1 inch)

=
`(1)/(240)` × (1 inch)
