Question

A block of wood is 2.5 feet long, 0.5 feet wide, and 0.25 feet tall. It weighs 16.5 pounds.

To the nearest pound, what is its density in pound per cubic feet?

Answer 1

Density = 52.8 pound per cubic feet.

Explanation:

Given the following data;

Length = 2.5 feet

Width = 0.5 feet

Height = 0.25 feet

Mass = 16.5 pound

To find the density of the wood;

First of all, we would determine the volume of the wood.

Volume = length * width * height

Volume = 2.5 * 0.5 * 0.25

Volume = 0.3125 cubic feet

Next, we find the density;

Mathematically, density is given by the formula;

Density = mass/volume

Substituting into the formula, we have;

Density = 16.5/0.3125

Density = 52.8 pound per cubic feet.
