Question

7 a block of lead has dimensions of 4.50 cm by 5.20 cm by 6.00 cm and weighs 1587 g. calculate its density. a 12.00 g/cm³ b 10.14 g/cm³ c 11.34 g/cm³ d 11.32 g/cm³

Explanation:

Step1: Calculate volume of the lead block

$V = 4.50\times5.20\times6.00=140.4\ cm^{3}$

Step2: Calculate density using formula $

ho=\frac{m}{V}$
$
ho=\frac{1587}{140.4}=11.3034\ g/cm^{3}\approx11.32\ g/cm^{3}$

Answer:

D. $11.32\ g/cm^{3}$
