Question

A rectangular block of copper metals weigh 673.37g. The dimensions of the block are 8.4cm by 5.5cm by 4.6cm. From this data, what is the density of the copper?

Answer 1

Density is g/cm^3 so you get the volume of the block:
4.6×5.5×8.4= 212.52cm^3


Then you take grams÷cm^3:

`\frac{673.37g}{212.52 {cm}^(3) } = \frac{3.168501g}{1 {cm}^(3) } = \frac{3.17g}{ {cm}^(3) }`
