6th Grade Math Formulas Quiz

1. The area of a Square is...

Side × side

Side + side

Side - side

Side × side × side

The area of a square is calculated by multiplying the length of one side by itself. This is because all sides of a square are equal in length. Therefore, to find the area, we simply multiply the length of one side by itself, resulting in side × side.

Explanation

The area of a square is calculated by multiplying the length of one side by itself. This is because all sides of a square are equal in length. Therefore, to find the area, we simply multiply the length of one side by itself, resulting in side × side.

2. What is the perimeter of a square?

2 x side

3 x side

4 x side

8 x side

The perimeter of a square is the sum of all its sides. Since a square has four equal sides, the correct answer is 4 x side, where "side" represents the length of one side of the square.

Explanation

The perimeter of a square is the sum of all its sides. Since a square has four equal sides, the correct answer is 4 x side, where "side" represents the length of one side of the square.

3. Length × Breadth is...

Area of a rectangle

Area of a triangle

Area of a circle

None of these

The formula for calculating the area of a rectangle is length multiplied by breadth. Therefore, the correct answer is "Area of a rectangle".

Explanation

The formula for calculating the area of a rectangle is length multiplied by breadth. Therefore, the correct answer is "Area of a rectangle".

4. For the area of a parallelogram, what's the formula?

B= (AH)

A= (BH)

H= (BA)

A= (2BH)

The formula for finding the area of a parallelogram is A = base x height. In this case, the base is represented by B and the height is represented by H, so the correct formula is A = BH.

Explanation

The formula for finding the area of a parallelogram is A = base x height. In this case, the base is represented by B and the height is represented by H, so the correct formula is A = BH.

5. 1 gram is equal to...

100 milligrams

1000 milligrams

1024 milligrams

2000 milligrams

The correct answer is 1000 milligrams because there are 1000 milligrams in 1 gram. This is a standard conversion in the metric system, where milli- represents one thousandth of a unit. Therefore, when converting grams to milligrams, you multiply the number of grams by 1000.

Explanation

The correct answer is 1000 milligrams because there are 1000 milligrams in 1 gram. This is a standard conversion in the metric system, where milli- represents one thousandth of a unit. Therefore, when converting grams to milligrams, you multiply the number of grams by 1000.

6. 3 feet are equal to...

A kilometer

A mile

A yard

An inch

Three feet are equal to a yard. A yard is a unit of length in the imperial system and is equal to three feet. This means that if you have three feet, you can also express it as one yard.

Explanation

Three feet are equal to a yard. A yard is a unit of length in the imperial system and is equal to three feet. This means that if you have three feet, you can also express it as one yard.

7. What is this "A= (BH) / 2" used for?

To know the area of a triangle.

To know the third angle of a triangle.

To know the area of a square.

To know the area of a circle.

The formula A = (BH) / 2 is used to calculate the area of a triangle. This formula represents the product of the base (B) and the height (H) of the triangle divided by 2. By substituting the values of the base and height into the formula, one can easily determine the area of the triangle.

8. What is the perimeter of a circle?

1.5 2 pi r

Pi r

2 pi r

None of these

The perimeter of a circle is the distance around the circle. It is calculated using the formula 2πr, where r is the radius of the circle. This formula represents the circumference of the circle, which is the same as its perimeter. Therefore, the correct answer is 2πr.

Explanation

The perimeter of a circle is the distance around the circle. It is calculated using the formula 2πr, where r is the radius of the circle. This formula represents the circumference of the circle, which is the same as its perimeter. Therefore, the correct answer is 2πr.

9. There are how many yards in a mile?

1000

1300

1560

1760

There are 1760 yards in a mile.

Explanation

There are 1760 yards in a mile.

10. "A = B+H" is the formula...

To know the area of a triangle.

To know the third angle of a triangle.

To know the area of a circle.

None of these

The formula "A = B+H" does not correspond to any of the given options. It is not used to calculate the area of a triangle, the third angle of a triangle, or the area of a circle. Therefore, the correct answer is "None of these".

Explanation

The formula "A = B+H" does not correspond to any of the given options. It is not used to calculate the area of a triangle, the third angle of a triangle, or the area of a circle. Therefore, the correct answer is "None of these".
