Jerry wants to wrap a present in a box for his mother. The box measures 10 cm wide, 4 cm high, and 17 cm long. How much wrapping paper will Jerry need to wrap the present?
To calculate the amount of wrapping paper needed, we need to find the surface area of the box.
Surface area of a rectangular box = 2(lw + lh + wh)
l = 17 cm
w = 10 cm
h = 4 cm
Substituting the values in the formula, we get:
2(17x10 + 17x4 + 10x4)
= 2(170 + 68 + 40)
= 2(278)
= 556 cm²
Therefore, Jerry will need 556 cm² of wrapping paper to wrap the present.
erry wants to wrap a present for his mother. The box he has measures 10 cm wide, 4 cm high, and 17 cm long. To calculate the amount of wrapping paper he needs, he has to find the surface area of the box.
The surface area of a rectangular box can be calculated by using the formula:
Surface Area = 2lw + 2lh + 2wh
where `l` is the length, `w` is the width, and `h` is the height of the box.
Substituting the given values, we get:
Surface Area = 2 x 10 x 17 + 2 x 10 x 4 + 2 x 4 x 17
Surface Area = 340 + 80 + 136
Surface Area = 556 cm^2
Therefore, Jerry needs 556 square centimeters of wrapping paper to wrap the present.
To calculate the amount of wrapping paper Jerry will need, we first need to find the surface area of the box.
The box has six sides, each with a different size:
1. Top and bottom: The top and bottom of the box have the same dimensions, so we only need to calculate one of them. The surface area of one top or bottom side is: length * width.
Top/bottom area = 17 cm * 10 cm
2. Front and back: The front and back sides also have the same dimensions, so we only need to calculate one of them. The surface area of one front or back side is: length * height.
Front/back area = 17 cm * 4 cm
3. Sides: There are two sides to consider, so we need to calculate the surface area of one side and then multiply it by 2. The surface area of one side is: width * height.
Side area = 10 cm * 4 cm * 2
Now, let's calculate the total surface area of the box by adding up all the sides:
Total surface area = (Top/bottom area) + (Front/back area) + (Side area)
Total surface area = (17 cm * 10 cm) + (17 cm * 4 cm) + (10 cm * 4 cm * 2)
Total surface area = 170 cm^2 + 68 cm^2 + 80 cm^2
Total surface area = 318 cm^2
So, Jerry will need 318 cm^2 of wrapping paper to wrap the present.
To find out how much wrapping paper Jerry will need, we need to calculate the surface area of the box.
The formula for the surface area of a rectangular prism (which is the shape of the box) is:
Surface Area = 2 * (length * width + length * height + width * height)
Let's calculate the surface area using the dimensions given:
Surface Area = 2 * (10 cm * 17 cm + 10 cm * 4 cm + 17 cm * 4 cm)
First, let's calculate the values inside the brackets:
10 cm * 17 cm = 170 cm²
10 cm * 4 cm = 40 cm²
17 cm * 4 cm = 68 cm²
Now, let's calculate the surface area:
Surface Area = 2 * (170 cm² + 40 cm² + 68 cm²)
Surface Area = 2 * 278 cm²
Surface Area = 556 cm²
Therefore, Jerry will need 556 square centimeters of wrapping paper to wrap the present.
