Question

the mass of a bowling ball is 13 lbs and the volume is 102 in³. how many lbs per cubic inch is its density? round to the nearest hundredth.
0.13 lbs/in³
1326 lbs/in³
7.85 lbs/in³
0.31 lbs/in³

Explanation:

Step1: Recall density formula

Density $
ho=\frac{m}{V}$, where $m$ is mass and $V$ is volume.

Step2: Substitute given values

$m = 13$ lbs, $V=102$ in³, so $
ho=\frac{13}{102}$.

Step3: Calculate and round

$\frac{13}{102}\approx0.13$ lbs/in³

Answer:

A. $0.13$ lbs/in³
