Question

A block of metal has dimensions of 2.00 x 5.50 x 1.25 cm. It has a mass of 37.1 grams. What is its density? 0.372 g/cm 3 2.69 g/cm 3 512 g/cm 3 4.24 g/cm 3

Answer 1

Answer:

Density of metal is $2.69 g/cm^3$

Explanation:

Volume of the metal V= lbh

Length l=2 cm

Breadth b= 5.5 cm

Height h=1.25 cm

Volume is

$V=lbh=2 \times 5.5 \times 1.25\\V=13.75 cm^3$

Density =Mass/ Volume

$\rho=\frac{m}{v} \\\rho=\frac{37.1}{13.75} \\\rho=2.69 g/cm^3$

Density of metal is $2.69 g/cm^3$
