27. What is the formula to find the area of a rectangle?
28. What is the formula to find the area of parallelogram?
29. Find the length of a rectangle with the longest side being 32 m and shortest side 20m.
30. What is the SI unit of volume?
31. which of the following cannot be used to find the space occupied by matter?
32. Find the volume of cuboid measuring 4 m by 18 m by 5 m.
33. which of the formulas below can be used to find the volume of a cylinder?

35. 1 grams per cubic centimeters is equivalent to?
36. The density of kerosene is 0.8 grams per cubic centimetres.Express this density in kilograms per cubic metres.
37. The volume of 2720 g of mercury was found to be 200 cubic centimetres.Calculate the density of mercury.
38. What information is not found in packing labels ?
39. What is the first step in the scientific method?
Asking a question is the first step in the scientific method because it helps define the problem or area of study that needs to be investigated.
40. Which of the following is NOT a valid variable in an experiment?
A subjective variable is based on personal opinions or feelings and is not consistent or measurable. In a scientific experiment, variables should be measurable and quantifiable.
41. What is a hypothesis?
A hypothesis is a testable prediction or explanation based on observations and prior knowledge. It is used to guide the experiment and make predictions about the outcome.
42. Why is it important to have a control group in an experiment?
A control group is necessary in an experiment to provide a baseline for comparison. By comparing the results of the experimental group to the control group, scientists can determine the effect of the independent variable.
43. What is the purpose of conducting experiments in science?
The purpose of experiments in science is to gather data and evidence that either supports or refutes a hypothesis. This allows scientists to draw conclusions based on empirical evidence.
44. Which type of graph is best used to show trends over time?
A line graph is ideal for showing trends over time because it visually displays the relationship between two variables over a continuous range.
45. What is the purpose of peer review in scientific investigation?
Peer review is a process where experts in the same field evaluate and critique a research paper before it is published. This helps ensure the quality and accuracy of the research findings.
46. Which of the following is NOT a valid scientific measurement unit?
Gallons are a unit of volume commonly used for measuring liquids, but they are not a standard scientific measurement unit. In science, the metric system is typically used for measurements.
47. What is the final step in the scientific method?
Sharing results is the final step in the scientific method because it allows other scientists to evaluate and replicate the experiment, verify the findings, and contribute to the body of scientific knowledge.
48. Which of the following is an example of a qualitative observation?
A qualitative observation uses the five senses to describe properties or qualities of an object, such as color, texture, or smell. In this case, 'blue' is a qualitative observation.
