Suppose that we want to send a parcel in the shape of a square-based rectangular solid, and the Standard Post service limits the sum of the length and girth (girth = the perimeter of the base) to 106 inches. Find the dimensions of the package of the greatest volume under these conditions. Write the exact answer. Do not round ___inches by______inches by_____inches
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.
Suppose that we want to send a parcel in the shape of a square-based rectangular solid, and the Standard Post service limits the sum of the length and girth (girth = the perimeter of the base) to 106 inches. Find the dimensions of the package of the greatest volume under these conditions. Write the exact answer. Do not round
___inches by______inches by_____inches
Given that the base is square shaped. Let x be the dimension of one side of the base.
Then, girth = perimeter of the base = 4x
Let l be the length. Sum of length and girth limits to 106 inches.
Since to find the maximum volume, take gives l=106-4x.
