Determine the perimeter of a heart-shaped box with sides measuring 6 cm and 8 cm.

To determine the perimeter of the heart-shaped box with sides measuring 6 cm and 8 cm, we first need to calculate the total length around the shape. The perimeter of a heart shape is the sum of the lengths of its sides. Since a heart shape is made up of two semi-circles and two straight sides of equal length, we can calculate the perimeter using the formula: perimeter = 2 * pi * (r + h), where r is the radius of the semi-circles (half of the side length) and h is the length of the straight side. In this case, the radius (r) is 3 cm (half of 6 cm) and the straight side (h) is 8 cm. Plugging in the values, we get perimeter = 2 * pi * (3 + 8) = 2 * pi * 11 ? 69.12 cm. Therefore, the perimeter of the heart-shaped box is approximately 69.12 cm.

Calculate the total number of chocolates if each box contains 12 chocolates and there are 6 boxes in total.

The total number of chocolates would be 72 (12 chocolates per box multiplied by 6 boxes).

Find the area of a rectangle with length 9 cm and width 5 cm.

To find the area of a rectangle, you multiply its length by its width. In this case, the length is 9 cm and the width is 5 cm. Multiplying 9 cm by 5 cm gives an area of 45 square centimeters. Therefore, the area of the rectangle is 45 square centimeters.

If a bouquet contains 15 red roses and 12 white roses, what is the ratio of red roses to white roses?

Mrs. Smith buys 3 Valentine's Day balloons for each student in her class. If there are 24 students, how many balloons did she buy in total?

The ratio of girls to boys in a classroom is 3:2. If there are 15 boys, how many girls are there?

There are 22 girls in the classroom. We can solve this by setting up the ratio as 3:2, which means for every 3 girls, there are 2 boys. Since there are 15 boys, we can calculate the number of girls by multiplying 15 boys by the ratio (3 girls/2 boys), which gives us 22 girls in total.
