Answer:
0.002 BTUs per cubic foot heat is produced per hour
Step-by-step explanation:
Given:
Number of person = 2
Amount of heat produced by one person = 2.400 BTU
Dimension of the room = 20 ft x 12 ft x 10 ft
To Find:
How many BTUs per cubic foot do they produce in 1 hour = ?
Solution:
E =
Substituting the values
E = 
E = 
E = 0.002 BTU per cubic feet
Combine like terms the solve. For example:
5x + 20x = 100
25x = 100
/25 = /25
x =4
see the attached figure to better understand the problem
we know that
The point G is where all medians intersect and is often described as the triangle's center of gravity or centroid. It is formed by the intersection of the medians. The centroid divides each median in a ratio of
