Area and Volume

Find the volume of a cube with a side length of 5 cm.

• 25 cm³

• 125 cm³

• 75 cm³

• 100 cm³

Answer explanation

To find the volume of a cube, you cube the side length. Volume = side length^3 = 5^3 = 125 cm^3. Therefore, the correct answer is 125 cm^3.

What is the area of a rectangle with a length of 8 cm and a width of 5 cm?

Answer explanation

To find the area of a rectangle, multiply the length by the width. Area = length x width = 8 cm x 5 cm = 40 cm^2. Therefore, the correct answer is 40 cm^2.

A triangle has a base of 10 cm and a height of 6 cm. What is its area?

Answer explanation

The area of a triangle is calculated using the formula: Area = 0.5 * base * height. Substituting the values, Area = 0.5 * 10 cm * 6 cm = 30 cm^2. Therefore, the correct answer is 30 cm^2.

If a rectangle has an area of 56 cm² and a width of 7 cm, what is its length?

• 8 cm

• 49 cm

• 63 cm

• 4 cm

Answer explanation

To find the length of the rectangle, divide the area by the width: 56 cm^2 / 7 cm = 8 cm. Therefore, the length of the rectangle is 8 cm.

• 5 cm

• 10 cm

• 20 cm

• 100 cm

Answer explanation

The area of a triangle is calculated using the formula: Area = 0.5 * base * height. Given area = 50 cm^2 and base = 10 cm, height = 2 * (Area / base) = 2 * (50 / 10) = 20 cm.

Calculate the area of a rectangle with dimensions 12 cm by 3 cm.

Answer explanation

To calculate the area of a rectangle, multiply the length by the width. In this case, 12 cm * 3 cm = 36 cm^2. Therefore, the correct answer is 36 cm^2.

A triangle has a height of 8 cm and a base of 5 cm. What is the area?

Answer explanation

The area of a triangle is calculated using the formula: Area = 0.5 * base * height. Substituting the values, we get: Area = 0.5 * 5 cm * 8 cm = 20 cm^2. Therefore, the correct answer is 20 cm^2.

If the length of a rectangle is tripled and its width is doubled, how does the area change?

• The area is doubled.

• The area is tripled.

• The area is six times larger.

• The area does not change.

Answer explanation

When the length of a rectangle is tripled and its width is doubled, the area becomes 6 times larger because the area of a rectangle is calculated by multiplying its length and width.
