What is the length of a cube if the volume is 27?

Therefore the lengths of the edges of a cube with a volume of 27 cm^3 is 3 cm.

How do you find the length of each edge of a cube?

The volume of a cube is length x width x height. Since it’s a cube, though, the length, width, and height are all equal, and equivalent to the length of one edge of the cube. Therefore, to find the lenght of an edge of the cube, just find the cube root of the volume. In this case, the cube root of 512 is equal to 8.

What is cube length?

Since the volume of a cube is length times width times height, with every measurement being the same, we just need to take the cube root of the volume: Rounded to the nearest tenth, the length is 3.5 feet.

Which expression is the sum of cubes?

A polynomial in the form a 3 + b 3 is called a sum of cubes. A polynomial in the form a 3 – b 3 is called a difference of cubes.

What is the volume of a cube with sides 7 cm?

Solution: Given, the length of sides of the cube is 7 cm. We know, Volume of a cube = (length of sides of the cube) 3 Therefore, Volume, V = (7 cm) 3

What is the formula to find the volume of a cube?

Volume of Cube Formula. We can easily find the volume of the cube (V), by knowing the length of its edges. Suppose, the length of the edges of the cube is ‘a’. Then the V will be the product of length, height, and width. So, the volume of the cube formula is: Volume of a Cube = Length × Width × Height. V = a × a × a. V = a 3

Is the volume of a cube directly proportional to its edge?

The volume of a cube is a 3 which means v ∝ a. So, the volume of a cube is directly proportional to its edge. How many edges and faces are in a cube? In a cube, there are 12 edges and 6 faces.

What is the total length of a 72-dimensional cube?

When you say “total length ie 72”, if you mean that is the total of the three dimensions then: since it is a cube L, W, and D are equal, so for a total of 72, they must be 24 each. The volume of a cube is L*W*D, or 24*24*24 or 13824 cu cm or 0.013824 cu meters.
