Question

a brick has a mass of 2,400 grams. it has the shape of a rectangular prism with a length of 20 centimeters, a width of 10 centimeters, and a height of 5 centimeters. what is the density of the brick? use the keypad to enter your answer in the box. the brick has a density of g/cm³.

Explanation:

Step1: Calculate the volume of the brick

The volume \( V \) of a rectangular prism is given by \( V=\text{length}\times\text{width}\times\text{height} \).
Substituting the given values: \( V = 20\times10\times5=1000\space cm^{3} \)

Step2: Calculate the density

The formula for density \(
ho \) is \(
ho=\frac{\text{mass}}{\text{volume}} \).
Given mass \( m = 2400\space g \) and volume \( V=1000\space cm^{3} \), then \(
ho=\frac{2400}{1000}=2.4\space g/cm^{3} \)

Answer:

\( 2.4 \)
