There is a stack of five identical books. The height of the stack is measured to be 8.6 cm, correct to the nearest 0.1 cm. Find the lower limit and upper limit of the height of one book.
Solution
Hints:
1.71 cm to 1.73 cm
For one book, divide the stack limits by 5. Lower limit = \\frac{8.55}{5} = 1.71 \\text{ cm}, upper limit = \\frac{8.65}{5} = 1.73 \\text{ cm}.
