All the surfaces of the lantern will be made of paper. What is the least amount of paper needed to make the lantern?
about that much
About what much? Please clarify.
Since you didn't give any measurements, the best answer I can give is about that much.
12, 6, 6 cm
2 (12 * 6) = _____ sq. cm
2 (12 * 6) = ______ sq. cm
2 (6 * 6) = _______ sq. cm
Add the products together.
To determine the least amount of paper needed to make the lantern, we first need to understand what shape the lantern takes. There are several common lantern shapes, such as cylindrical, cuboid, or spherical. Assuming the lantern is a regular cylinder, we can proceed with the calculation.
The surface area of a cylindrical lantern can be calculated using the formula:
Surface Area = 2πrh + πr^2,
where r is the radius of the lantern base and h is the height of the lantern.
To determine the least amount of paper needed, we need to minimize the surface area. To achieve this, we can calculate the partial derivatives of the surface area formula with respect to both r and h. By setting these derivatives equal to zero and solving the resultant system of equations, we can find the values of r and h that minimize the surface area.
However, since we don't have specific values for the lantern's dimensions, we are unable to provide an exact answer. If you have the specific dimensions (radius and height) needed for the lantern, please provide them, and we can calculate the least amount of paper required.
