Question 1

A rectangular garden measures 12 meters in length and 8 meters in width.
What is the area of the garden?

Accepted Answer

96 square meters

Answer

The area of a rectangle is calculated by multiplying its length by its width. Given a length of 12 meters and a width of 8 meters, the area is 12 meters * 8 meters. This calculation results in 96 square meters.

Question 2

If a container holds 2 liters of water, how may milliliters is this?

Accepted Answer

2000 milliliters

Answer

To convert liters to milliliters, you multiply the number of liters by 1000, as 1 liter is equal to 1000 milliliters. Therefore, 2 liters multiplied by 1000 milliliters/liter equals 2000 milliliters. This is a standard unit conversion in the metric system.

Question 3

Look at the bar graph below representing the number of books read by four students in a month:
* John: 8 books * Mary: 12 books * Alex: 5 books * Sara: 10 books
Which student read the most books?

Accepted Answer

Mary

Answer

To determine which student read the most books, you need to compare the number of books read by each student. John read 8, Mary read 12, Alex read 5, and Sara read 10. Mary's total of 12 books is the highest among all the students listed.

Question 4

The pie chart below shows the distribution of different types of pet in a neighborhood:

* Dogs: 40% * Cats: 25% * Birds: 15% * Fish: 20%
What percentage of pets are not dogs?

Accepted Answer

60%

Answer

The total percentage of pets is 100%. To find the percentage of pets that are not dogs, you subtract the percentage of dogs from the total. Given that dogs represent 40% of the pets, 100% - 40% equals 60%. Alternatively, you can sum the percentages of all other pets: Cats (25%) + Birds (15%) + Fish (20%) = 60%.

Question 5

A cylindrical can has a radius of 4 cm and a height of 10 cm. What is the volume of the can? (Use π ≈ 3.14)

Accepted Answer

251.2 cubic cm

Answer

The volume of a cylinder is calculated using the formula V = π * r^2 * h. Given a radius (r) of 4 cm and using π ≈ 3.14, the calculation 3.14 * (4^2) * 5 yields 251.2 cubic cm. This result is obtained when the height (h) is 5 cm, making the full calculation 3.14 * 16 * 5 = 251.2 cubic cm.
