How do you find the volume of a cube given the perimeter?
Its volume is given by $V=lbh$ . Cube is a special case of cuboid when all the three variables become equal means $l=b=h$ . Hence, the volume of cube is given by $V={{a}^{3}}$ where a is its side length.
What is the volume of the cube if the perimeter of one face of the cube is 40?
If the perimeter of one face of a cube is 40 cm, it means the side of the cube is 40/4 = 10 cm. The volume of the cube is thus 10^3 = 1000 cc.
Which number is a perfect cube 25?
List of Perfect Cubes 1 to 50

|---|---|---|
| 23 | 23× 23× 23 | 12167 |
| 24 | 24× 24× 24 | 13824 |
| 25 | 25× 25× 25 | 15625 |
| 26 | 26× 26× 26 | 17576 |
How do you calculate the face of a cube?
Explanation: The surface area of a cube = 6a2 where a is the length of the side of each edge of the cube. Put another way, since all sides of a cube are equal, a is just the lenght of one side of a cube. We have 96 = 6a2 → a2 = 16, so that’s the area of one face of the cube.
What is the perimeter of each face of the cube?
The perimeter of each face will be 4*10 = 40 cm. The cube has 6 faces. But the total length of the edges will not be 6*40 or 240 cm but it will be just 10*12 = 120 cm because some edges will be common to 2 adjacent faces. 2k views.
How do you find the volume of a cube?
To find the volume of the cube, you must first find the length of a side. 1.) To find length of a side, you must take the given area, , and solve for the side: 2.) Next, solve for volume of the cube: 1.) A cube has 12 edges, so if each edge length is 5cm, then we can write as ;
How do you measure the side of a cube?
Measuring the side of the cube is easy. The result from the calculation, using our volume of a cube calculator or otherwise, will always be in the length unit used, cubed. So, if you measured it in inches, the result will be in cubic inches.
Does it matter which side of the volume equation is equal?
Since all sides are equal, it does not matter which side is given exactly. For example, if the length of a side is 5 inches, using the volume equation results in 5 3 = 5 x 5 x 5 = 125 in 3 (cubic inches).
