How do you find minimum surface area given volume?
For a square-based prism with a given volume, the minimum surface area occurs when the prism is a cube. Given a volume, you can find the dimensions of a square-based prism with minimum surface area by solving for s in the formula V = s3, where V is the given volume and s is the length of a side of the cube.
How do you minimize the surface area of a cylinder with a fixed volume?
So that’ll give you the top and bottom you multiply by two to account for the top and bottom together. So when we simplify we get two pi RH plus two PI R squared the formula.
How do you minimize the surface area of a rectangular prism with a fixed volume?
So there’s going to be four copies of x times y indeed if I try to fill in this front side here that’s going to be a height of Y in at a base of X. Ok. So that’s my surface.
What is the minimum surface area?
In mathematics, a minimal surface is a surface that locally minimizes its area. This is equivalent to having zero mean curvature (see definitions below).

How do you find the minimum surface area of a cuboid?
Let P be a parallelepiped of dimensions a,b,c, its volume is given by V=abc and its surface is S=2ab+2bc+2ac. Let us assume that V>0, then c=Vab and thus S=2ab+2Va+2Vb.
What minimizes surface area of a cylinder?
The Generalized Can Problem
It can be proven that the surface area of a can is minimized when the ratio of height to radius is 2, regardless of the volume. That is, for cylindrical cans with a fixed volume, when the height of the can is twice the radius, the surface area of the can will be minimized.
How do you find the total surface area of a cylinder?
Finally, the total surface area of the cylinder formula is simply the sum of the base surface area and the lateral surface area: total_area = base_area + lateral_area , or total_area = 2 * π * r² + (2 * π * r) * h , or total_area = 2 * π * r * (r + h) .

What shape has the smallest surface area to volume ratio?
a sphere
Of all the shapes, a sphere has the smallest surface area for a given volume.
What is the formula for surface area?
Surface Area Formulas:
| Shape | Lateral Surface Area (LSA) | Total Surface Area (TSA) |
|---|---|---|
| Right Prism | Base perimeter × Height | LSA + 2 (area of one end) |
| Right Circular Cylinder | 2πrh | 2πr(r + h) |
| Right Pyramid | (1/2) Perimeter of base × Slant Height | LSA + Area of Base |
| Right Circular Cone | πrl | πr(l + r) |
Which of the following has the maximum volume with minimum surface area?
A figure is in 2 dimensions while volume is of an object in 3 dimensions. A figure with maximum area and least perimeter is a circle. A sphere has maximum volume for minimum surface area.
How do you find the minimum surface area of a cylinder?
It can be proven that the surface area of a can is minimized when the ratio of height to radius is 2, regardless of the volume. That is, for cylindrical cans with a fixed volume, when the height of the can is twice the radius, the surface area of the can will be minimized.
What is the surface area of a closed cylinder?
Total surface area of a closed cylinder is: A = L + T + B = 2πrh + 2(πr2) = 2πr(h+r)

Which shape has minimum surface area and why?
Rain drops or bubbles of any kind which form are always of a spherical shape. This is because the liquid tries to minimize the surface area as the molecules on the surface have higher potential energy. The shape which most efficiently manages to do this is a sphere.
Which of the following has the smallest surface area?
Of all the shapes, a sphere has the smallest surface area for a volume.
What are the formulas of surface area and volume?

Why surface area of sphere is minimum?
Geometrical approach: Each point on the surface of a sphere is at an equal distance (equal to radius) from the center this results in the minimum surface area for a given volume.
Does a cylinder have least surface area?
A closed cylinder of given volume will have least surface area when the ratio of its height and base radius is.
