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.

The spherical storage tank described in Example 5 had
a length of radius of 3 ft. Because the tank needs to be
painted, we need to find its surface area. Also determine
the number of pints of rust-proofing paint needed to paint
the tank if 1 pt covers approximately 40 ft. Use your

calculator.
36. An observatory has the shape of a
right circular cylinder surmounted
by a hemisphere. If the radius of
the cylinder is 14 ft and its altitude
measures 30 ft, what is the surface
area of the observatory? If 1 gal of
paint covers 300 ft“, how many
