What is a 20 sided cube called?
Icosahedron
What is equal to the square root of 20?
4.4721359549995793928183473374626 and -4.4721359549995793928183473374626 The cube root of 400 is also equal to the square root of 20. (IIRC) Another way to approach it: √(20)=√(4x5) =2√(5)
How can you find the side of a cube using a cube root?
The cube root is the side of a cube.
What is Nets of a Cube?
Well, the nets of the cube are basically when you get a 3D cube and flatten it. That gives you the 2D shape of a cube, which is know as the net. There are 11 nets for a cube. Here they are.
How do you find the smallest positive integer of a variable in a cube root so that the cube root is an integer ex. find the smallest positive integer g so that the cube root of 400g is an integer?
Here is a method: cube root of 400g = n, where n is an integer cube both sides: 400g = n3 then: g = n3/400 therefore: n3/400 must be an integer if this is so, then n3 must be divisible by 400 with no remainder, and n must be => cube root of 400 which is 7.368 bracket the answer by substitution: let n=8, n cubed = 512 no good let n=12, n cubed = 1728 no good let n=20, n cubed = 8000, 8000/400=20 OK No smaller value of n will be divisible by 400 without a remainder, so g=20 is the smallest positive integer that meets the requirement.
