Question

Bernice is calculating the density of cookies in a tin. She knows the number of the cookies in the tin and the volume of the tin. Which of the following formulas can be used to calculate the density of the cookies in the tin?

A) Density = volume of tin/number of cookies
B) Volume of shelf = density/number of cookies
C) Number of books = density/volume of tin
D) Density = number of cookies/volume of tin

Answer 1

Option D) Density = number of cookies/volume of tin can be used to calculate the density of the cookies in the tin.

Step-by-step explanation:

The density of a substance can be calculated by dividing its mass by its volume. The volume of a cube is calculated by cubing the edge length.

Option D) Density = number of cookies/volume of tin can be used to calculate the density of the cookies in the tin. This formula divides the number of cookies by the volume of the tin.

For example, if Bernice knows the number of cookies in the tin is 20 and the volume of the tin is 10 cubic centimeters, she can calculate the density using the formula:

Density = 20 cookies / 10 cm³ = 2 cookies/cm³
