Q&A for How to Calculate the Volume of a Cube

The side length is the cube root of the volume.

Multiply the area of the bottom of the cube by 2.5.

First, you need to find the volume of the tank. This can be found by multiplying the length, height, and width altogether. When you do that, you get 4 cubic meters. Doing some research, you will find that 1 cubic meter is approximately equal to about 220 imperial gallons or 264.2 US liquid gallons. If you use the imperial gallons, then the tank would hold a little less than 880 imperial gallons. But if you use the US liquid gallons, it would hold slightly less than 1,057 gallons.

Good question. Assume that the circle fits perfectly into the cube. So that means the inside edges touch. You know that the circle had a diameter of 14. So if it fits perfectly into the cube, the cube would also have a side length of 14. So the volume could be easily calculated: 14 cubed, which is 2744.

Well, that isn't exactly a cube but the formula is similar. You just need to multiply the length, width, and height altogether. 8 x 6 x 2.5 is 120. And there you have it. 120cm cubed. It's cubed because the units are little cubes.

Divide the perimeter by 4. That gives you the length of one edge. Cube it. That's the volume.

3 cm will fit into the 15 cm dimension five times; it will fit into the 9 cm dimension three times; and it will fit into the 12 cm dimension four times. 5 x 3 x 4 = 60 cubical boxes.

We know that to find the volume of a cube, we cube one of its sides. So if we want to inverse or reverse that operation, we take the cube root of 1728. It happens that the cube root is 12. So we now know that the length of one side is 12. If the length of one side of the cube is 12, then the area of one face would be 144. A cube has 6 faces, so we need to multiply 144 by 6 which is 864.

It depends on the size of the blocks.

Find the cube root of the volume. That should equal the length of an edge.

It doesn't matter what unit of measurement you use. Volume equals the cube of the side length.

If you're asking about the length of an edge, it's the cube root of the volume. If you're asking about the area of a side, it's the square of the length of an edge.

Multiply length by width by height.

This is an algebra problem involving the simultaneous solution of two equations in two unknowns. The unknowns are the length (l) and width (w) of the rectangle. The product of the length and width (lw) is equal to the area (60). Express one dimension in terms of the other dimension: for instance, l = 60/w. Then use the Pythagorean theorem to find w by using (w + 8) to represent the diagonal (hypotenuse), (60/w) to represent the length, and, of course, (w) to represent the width.

Divide each dimension by 6 cm: 10, 9, and 5. Multiply those numbers to get 450 cubes.

(1/5)³ = (1/5)(1/5)(1/5) = 1/125 cubic inch.

Each side has an area of (20)(20) = 400 square centimeters. The total surface area is (6)(400) = 2400 square centimeters.

If the cube's volume is 64, the length, width and height are all the cube root of 64. The cube root of 64 is 4. The length, width, and height are 4 meters.
