Question

use the dimensions of the refrigerator shown below for your work.
if the refrigerator is advertised as a 19 - cu - ft refrigerator, how much space is taken up by the motor, insulation, and so on?
ft³

Explanation:

Step1: Convert inches to feet

Since \(1\) foot \( = 12\) inches.
For length \(l = 66\) inches, \(l=\frac{66}{12}= 5.5\) feet.
For width \(w = 33\) inches, \(w=\frac{33}{12}=2.75\) feet.
For height \(h = 36\) inches, \(h=\frac{36}{12}=3\) feet.

Step2: Calculate the total volume

The volume of a rectangular prism \(V=l\times w\times h\).
Substitute \(l = 5.5\), \(w = 2.75\), \(h = 3\) into the formula:
\(V=5.5\times2.75\times3\).
First, \(5.5\times2.75=(5 + 0.5)\times2.75=5\times2.75+0.5\times2.75=13.75+1.375 = 15.125\).
Then \(V=15.125\times3 = 45.375\) cubic - feet.

Step3: Calculate the space used by motor and insulation

The space used by motor and insulation \(=45.375-19=26.375\) cubic - feet.

Answer:

\(26.375\)
