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?

Density = 52.8 pound per cubic feet.

Step-by-step 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.

step-by-step explanation:

hi there!

step-by-step explanation:

a roof pitch is basically for every inch rise there is 12 inches run.

the height of the roof is also known as the rafter.

formula: rafter^2 = rise^2 + run^2

rafter^2 = 5^2 + 12^2

rafter^2 = 25 + 144

rafter ^2 = 169"^2

the height of the roof from the lowest point to the highest point is 169"^2.

hope this : )
