Example Question #12 : How To Find The Volume Of A Cube
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?
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.
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.
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.
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.
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.
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
Example Question #1 : Solve Problems Involving Area, Volume And Surface Area Of Two And Three Dimensional Objects: Ccss.Math.Content.7.G.B.6
The length of the side of a cube is . Give its surface area in terms of .
Substitute in the formula for the surface area of a cube:
Example Question #901 : Grade 7
If a cube has one side measuring cm, what is the surface area of the cube?
To find the surface area of a cube, use the formula , where represents the length of the side. Since the side of the cube measures , we can substitute in for .
Example Question #1 : How To Find The Surface Area Of A Cube
Your friend gives you a puzzle cube for your birthday. If the length of one edge is 5 cm, what is the surface area of the cube?
Your friend gives you a puzzle cube for your birthday. If the length of one edge is 5 cm, what is the surface area of the cube?
To find the surface area of a cube, use the following formula:
This works, because we have 6 sides, each of which has an area of
Plug in our known to get our answer:
