How do you calculate cube?
Formulas for a cube:
- Volume of a cube: V = a.
- Surface area of a cube: the area of each face (a x a) times 6 faces. S = 6a.
- Face diagonal of a cube: By the pythagorean theorem we know that. f2 = a2 + a. Then f2 = 2a.
- Diagonal of the solid cube: Again, by the pythagorean theorem we know that. d2 = a2 + f.
What are all the square roots of 81?
√81 = 3×3 = 9. Hence, the value of the square root of 81 is 9.
Is 81 a perfect square?
Informally: When you multiply an integer (a “whole” number, positive, negative or zero) times itself, the resulting product is called a square number, or a perfect square or simply “a square.” So, 0, 1, 4, 9, 16, 25, 36, 49, 64, 81, 100, 121, 144, and so on, are all square numbers.
Can the square root of 54 be simplified?
How do you simplify square root of 54? 3√6 is the simplest form of √54.
What are the two square roots of 81?
Explanation: 81=9⋅9 then the square root of √81=9 . Because the double multiplication for the same sign is always positive, the square root is also valid with the other sign 81=(−9)⋅(−9) then √81=−9 and we can say that √81=±9 .
