You are building a box to hold your collection of rare rocks. You want to build a cube-shaped box with a side length of 3 feet. If you do so, what will the volume of your box be?

Begin with the formula for volume of a cube:

Where s is our side length and V is our volume.

Now, we need to plug in our side length and solve for V

So, our volume is 

Example Question #17 : How To Find The Volume Of A Cube

Find the volume of a cube with a width of 9in.

Possible Answers:

Correct answer:

Explanation:

To find the volume of a cube, we will use the following formula:

where l is the length, w is the width, and h is the height of the cube.

 

Now, we know the width is 9in.  Because it is a cube, all sides are equal.  Therefore, the length and the height are also 9in.

Knowing this, we can substitute into the formula.  We get

Example Question #16 : Cubes

Find the volume of a cube with a height of 8in.

Possible Answers:

Correct answer:

Explanation:

To find the volume of a cube, we will use the following formula:

where l is the length, w is the width, and h is the height of the cube.

 

Now, we know the height of the cube is 8in.  Because it is a cube all sides (length, height, width) are the same.  So, all are 8in.

Now we can substitute.  We get

Example Question #12 : How To Find The Volume Of A Cube

Find the volume of a cube with a length of 5in.

Possible Answers:

Correct answer:

Explanation:

To find the volume of a cube, we will use the following formula:

where l is the length, w is the width, and h is the height of the cube.

 

Now, we know the length of the cube is 5in.  Because it is a cube, all sides/lengths are equal.  Therefore, the length and width are also 5in.

Knowing this, we can substitute into the formula. We get

Example Question #13 : How To Find The Volume Of A Cube

Find the volume of a cube with a height of 14cm.

Possible Answers:

Correct answer:

Explanation:

To find the volume of a cube, we will use the following formula:

where l is the length, w is the width, and h is the height of the cube. 

 

Now, we know the height of the cube is 14cm.  Because it is a cube, all sides (lengths, widths, heights) are equal.  Therefore, the length and the width are also 14cm.  So, we can substitute.  We get

Example Question #31 : Solid Geometry

Find the volume of a cube with a height of 7in.

Possible Answers:

Correct answer:

Explanation:

To find the volume of a cube, we will use the following formula:

where l is the length, w is the width, and h is the height of the cube.

Now, we know the height of the cube is 7in. Because it is a cube, all sides are equal. Therefore, all sides (the length, width, height) are all 7in. 

So, we get
