A parking lot is 400 yards long and 300 yards wide. You would want to make a miniature version of this in your production design course. If you make it 10 inches long, how wide should it be?
Unitary Method
The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.
Speed, Time, and Distance
Imagine you and 3 of your friends are planning to go to the playground at 6 in the evening. Your house is one mile away from the playground and one of your friends named Jim must start at 5 pm to reach the playground by walk. The other two friends are 3 miles away.
Profit and Loss
The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.
Units and Measurements
Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.

Ohm’s Law
- An 8-ohm loudspeaker is powered by 60 volts.
- How much amps will be produced? ____________________
- Suppose the loudspeaker requires 5 amps. Should the resistance be adjusted? If yes, what should be the amount of resistance? ____________________
Note:
V = I x R
Where V = voltage, in volts, I = current, in amps, R = Resistance, in ohms
