Question

. If the thickness of a paper sheet is 0.0016 cm, find the thickness of 100 sheets.
Express the answer in standard form.

Answer 1

Answer:0.16 cm

Step-by-step explanation:

Size of one sheet = 0.0016 cm

Number of sheets = 100

Thickness of sheets = 0.0016 × 100

= 0.16 cm

Answer 2

The thickness of 100 sheets is $(1.6\times 10^{-1})$ cm.

Tips:

When we write a number as a decimal number that lies between $1.0$ and $10.0$, multiplied by a power of $10$, is called to be in the standard form.

E.g., $0.0012=1.2\times 10^{-3}$

Step-by-step explanation:

Thickness of a paper is $0.0016$ cm

Then the thickness of $100$ sheets

$=100\times 0.0016$ cm

$=0.16$ cm

$=1.6\times 10^{-1}$ cm
