A spacecraft has landed on a strange flat object and has measured its density (103kg /m3) at several locations (Fig. 16). From photographs during the approach to the object scientists have estimated the thickness of the object to be about 1.4 m thick the area to be about 3500 m2 . Approximate the mass of the object.
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.

![**Object in Space: Figure 16**
This figure illustrates an abstract object in space, marked by a yellow irregular shape. The object contains several black dots, each associated with numerical values. These values denote specific data points or measurements within the object's spatial context, ranging from 7.2 to 8.5.
- The black dots are dispersed within the boundary of the object.
- The numbers adjacent to each dot represent corresponding values measured at those locations.
The data points are as follows:
- Top-left section (near the border): 7.9, 7.8, 7.5
- Central area: 8.5, 8.1, 7.8
- Lower section: 7.2
- Middle-right section: 8.3, 7.4
- Top-right section: 7.3
This graphical representation is used for demonstrating the spatial distribution of certain values across the object, providing a visual means to analyze the varying measurements in different regions.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fa31da2e8-f6c9-4547-af19-99126d862016%2Fb8f1ad59-9844-4b21-a7bc-925f5f6110ce%2Fj0wj4e8.png&w=3840&q=75)
