Question

the number of grains of sand in one cubic centermeter sample was 9.37 x 10 cubed. how many grains of sand would be in a cubic meter of sand

Answer 1

This is a basic unit conversion problem. You need to know that 1 m = 100 cm, or expressed as a fraction, \[\frac{1\text{ m}}{100\text{ cm}} =1\]

Now put that in the expression:

\[9.37*10^3 \frac{\text{grains}}{ \text{ cm}^{3}} * 1 \text{m}^3 * (\frac{100\text{ cm}}{1\text{ m}})^3\]Notice how the units of length cancel out, leaving only grains.

Answer 2

so there's no answer or is there an answer

Answer 3

Evaluate that expression...

9.37 * 10^3 * 1 * (100/1)^3 = ?

Answer 4

\[9.37*10^3 \frac{\text{grains}}{ \text{ cm}^{3}} * 1 \text{m}^3 * (\frac{100\text{ cm}}{1\text{ m}})^3= \]\[9.37*10^3\frac{\text{grains}}{ \text{ cm}^{3}}*1\text{m}^3 *100^3\text{ cm}^3/(1^3 \text{ cm}^3)=\]\[9.37*10^9 \text { grains} \]

ohhh thanks(:
