Square roots and cube roots are mathematical operations that help us find the value that, when multiplied by itself (for square roots) or multiplied by itself twice (for cube roots), gives a specific number. They are useful in various fields such as engineering, physics, and computer science for calculations involving areas, volumes, and complex equations. Understanding square roots and cube roots allows for solving equations, simplifying expressions, and analyzing data more efficiently.

How do you evaluate a square root?

You know to find out which out which number has been timed by itself to make the number in the square root. For example: If the number inside the square root is 49, you need to find out which number has been timed by itself to make 49. As you may know, the number inside the square root is always a square number, so I would advise you to learn the list of square numbers. 7 x 7= 49, so the square root of 49 is 7. Remember that Evaluate simply means work out. So when to asked to evaluate a square number, cube number, square root, cube root etc., simply just work it out. Evaluating powers and roots is grade D in maths.


How many 10 by 10 grids would you need to make a thousand cube?

10 grids, stacked, would make a thousand cube.


Is 196 perfect square or perfect cube?

196's prime numbers are (2) (2) (7) (7). For example, if you square those prime numbers you would get 14. Why? Because u need equal integers within a square root, so that you can take that integer outside the square root. With the same knowledge, we can apply ask the question whether 196 is a cube root. If it's a cube root, then it needs to have 3 same integer (ex: 3x3x3x4x4x4x; 2x2x2x7x7x7). As you can see we don't have third same integer. Also, even if it is 2x2x2x7x7, it cannot be a cube root because it is missing the third 7. So the answer is that 196 is a perfect square and not a perfect cube. Note: you cannot have a square root of a negative integer, if the question is "is -196 a perfect square or a perfect cube", then the answer is neither. Of course you can SQUARE the negative number (ex: (-2)^2=+/- 4), but you cannot mathematically square root a negative number unless your using the imaginary integer "i". I hope it answers your question and just a bit more.


How many vertices are in a 3-D square?

A vertex is defined in Geometry and the point at which two lines or segments connect. If we think of a 2D square first we can count that it in fact has 4 vertices. One at the top left, one at the top right, one at the bottom left, and one at the bottom right. We understand in Geometry that a 3D object is a 2D object with an additional plane of space. So knowing this we can assume that there would have to be an additional 4 vertices to formulate a 3 Dimensional square - which is now a cube. So in conclusion If a 2D object has 4 vertices, then a 3D object since it has an additional plane of space would need an additional 4 vertices to make a square on the second plane of space. So we need a total of 8 vertices to make a 3D cube (3D square - though in technicality a square is 2D, a cube is 3D)

What is the minimum amount of paper needed to cover all 6 faces of a cube with 512 cubic centimeters?

To cover all 6 faces of a cube with 512 cubic centimeters, you would need at least 3 square feet of paper. Each face of the cube would require a square piece of paper with a side length equal to the square root of the cube's volume, which in this case is the cube root of 512 or 8.

What is the surface area of the cube below?

To calculate the surface area of a cube, you need to find the area of all six faces and then sum them up. Since all faces of a cube are identical squares, you can use the formula for the area of a square, which is side length squared. So, if the side length of the cube is "s," the surface area would be 6s^2.

A cube with 2 inch sides is placed on a cube with 3 inch sides then a cube with 1 inch sides is placed on the 2 inch cube what is the surface area of the 3 cube tower?

To find the total surface area of the 3-cube tower, we need to calculate the surface area of each cube individually and then add them together. The surface area of a cube is given by 6 times the side length squared. For the 3-inch cube: 6 * 3^2 = 54 square inches For the 2-inch cube: 6 * 2^2 = 24 square inches For the 1-inch cube: 6 * 1^2 = 6 square inches Adding these together: 54 + 24 + 6 = 84 square inches Therefore, the total surface area of the 3-cube tower is 84 square inches.


Why is the use of square roots important?

Because it's a faster way of grouping numbers together.

How is combining like terms similar to adding and subtracting square roots?

In surd form, square roots need to be have the same radical term before you can add or subtract them. However, unlike in algebraic expressions, it is possible to add or subtract square roots using approximate (decimal) values.


How do you find the two square roots in a number?

Use a calculator (if you need) to find the principal square root. The second square root is the negative of the number.


How do you calculate area of one side of a cube?

To calculate the area of one side of a cube, you need to find the area of one of the square faces. Since all sides of a cube are equal in length, you can use the formula for the area of a square, which is side length squared. Therefore, to find the area of one side of a cube, you simply square the length of one side of the cube.
