Question

i need to fin the smallest possible surface area of any 3D shape but it has to have a volume of 1200cm3

Answer 1

Spheres have the smallest surface area to volume ratio.

Volume of a sphere=(4/3)pi*r^3

plug in 1200
1200=(4/3)pi*r^3

Find the radius by solving for r

Surface Area of a Sphere=4*pi*r^2

Once you've found r, plug it into this equation to find the corresponding surface area.
