Question

A typical dollar bill is 15.50 cm by 6.50 cm.
Calculate the surface area in square meters, square centimeters and square nanometers

Answer 1

Answer:

• 0.010075 m²

• 100.75 cm²

• 1.0075x10¹⁶ nm²

Explanation:

As the measurements are given to us in centimeters, let's start by calculating the surface area in square centimeters:

• Area = 15.50 cm * 6.50 cm = 100.75 cm²

Now we convert 100.75 cm² to m², as follows:

• 100.75 cm² * $(\frac{1m}{100cm}) ^2$ = 0.010075 m²

Finally we convert 0.010075 m² to nm², as follows:

• 0.010075 m² * $(\frac{1nm}{1x10^{-9}m}) ^2$ = 1.0075x10¹⁶ nm²
