No. Relative to its volume, the greater the number of sides, the smaller the volume. In the limit, a cylinder (circular prism, with an infinite number of "sides") will have the least surface area.
It depends on the shape of the base, but yes it has at least 3 triangular faces!(yes)
Yes - if you define an equilateral triangle as one in which at least two sides are equal.
No. A non-convex polygon must have at least one reflex angle (between 180 and 360 degrees). But by equiangularity, all the angles of the polygon would have to be reflex. On a plane surface this is not possible.
equilateral triangles and isosceles ones
An isosceles triangle has at least two congruent sides. An equilateral triangle has three congruent sides. So, an equilateral triangle is a special case of isosceles triangles. Since the equilateral triangle has three congruent sides, it satisfies the conditions of isosceles triangle. So, equilateral triangles are always isosceles triangles. Source: www.icoachmath.com
wet surfaces like tiles have the least amount oof friction

It has to do with volume vs surface area. All things lose heat through the surface. The bigger the surface, the more heat lost. An animal curled into a ball presents the least amount of surface area for its volume, which means it takes the least amount of energy to keep warm.
Equilateral triangles have three congruent sides. That's the definition of an equilateral triangle. If it doesn't have three congruent sides, then it's not an equilateral triangle.
False...an equilateral triangle has 3 equal sides.
yes, it has at least three
It depends on the shape of the base, but yes it has at least 3 triangular faces!(yes)
Yes - if you define an equilateral triangle as one in which at least two sides are equal.
so you can use the least amount of paper to make the box. or wrap the box.
