# Math Help - Density of Human Body Question

1. ## Density of Human Body Question

The density of the human body is estimated to be 0.95 g/cm^3
Calculate the volume of a person wighing 79.99kg
Express your answer in the form a x 10^n, where n is and element of N and 1 <a<10

2. ## Well

0.95g = 1cm^3 = 0.00095kg
79.99kg = x cm^3

$\frac{79.99}{0.95}$=what you want
u know how to convert that to the notation needed?

Density is defined by: $density = \dfrac{mass}{volume}$ thus $volume = \dfrac{mass}{density}$ .

$V=\dfrac{79.99\ kg}{0.95\ \frac{g}{cm^3}}$
$V=\dfrac{79990\ g}{0.95\ \frac{g}{cm^3}}=84200\ cm^3$
