Q&A for How to Calculate the Volume of a Rectangular Prism

You have to know the height. Otherwise, you'd have to say the volume is 675x cubic units.

Remember that length x width x height. A rectangular prism that is five inches high, ten inches long, and two inches deep will have a volume of 100 square in. 5x10x2=100.

The rectangle's area, times the prism's height vertical to the rectangle, gives the volume; various combinations of dimensions give the same volume, so if you know the volume, and want the dimensions, you will find many sets of dimensions. For example volume 24 could give the length, width, and height of 2, 2, and 6; or 2, 3, 4; or 1, 1, 24; and so on.

There are 1,000 cubic centimeters in one liter. So divide the number of cubic centimeters you have by 1,000 to get the number of liters.

Divide the volume by the length, and then divide that by the height. Alternatively, multiply the length and the height, and then divide the volume by that number.

Find the volume of one cube, then multiply that by the number of cubes. You could also find the volume of the rectangular prism, including the missing cubes, then subtract the volume of the cubes missing.

It refers to the three-dimensional space that an object occupies.

There are three different faces on a rectangular prism. Calculate each by multiplying the length by width, add the three results together and multiply by 2 to work out the total area.

No. Volume is expressed in units cubed.

Multiply the three dimensions together to get cubic centimeters, then divide by 1,000 to get liters.

You can either find the area of a triangle or the volume of a triangular prism or pyramid. Triangles are 2d, so you find the area. To find the area of a triangle, multiply length by height and divide by two (l x h /2). To find volume of a triangular prism, you take the area of the face (triangle) and multiply it by the width.

Each cubic inch contains 0.554 fluid ounce.

Assuming all the stairs are identical, measure the length and width of one stair, multiply the dimensions together to get the area of one stair, then multiply by the number of stairs.

That may refer to the inside dimensions rather than the outside dimensions.

There are eight corners in a rectangular prism. Each corner has three right angles (between the various sides).

First, find the volume of the house itself which is length times width times height. Then, find the volume of the roof which is the base of the triangle times the height of the triangle. Next, multiply that number by the height of the prism. Add the volume of the house and the volume of the roof.

For the volume of a rectangular prism, you just multiply the 3 measurements together: 72 x 24 x 28 = 48,384, but remember to add on the unit - metres cubed (m^3), etc.

Multiply length by width by height (volume in cubic feet), then multiply by 28.32 (volume in liters).

If you're missing the length, width, or height of a rectangular prism, you cannot calculate its volume.

If one edge of the cube is 20 cm long, the volume of the cube (and the rectangular solid) is 20³ or 8,000 cubic cm. Multiply the two known dimensions of the solid: 25 x 10 = 250 sq cm. Divide 250 into 8,000 = 32 cm, the height of the solid.

Here's how to calculate the surface area of a rectangular prism: Let l be the length, w the width, and h the height. The area is: 2(lw) + 2(lh) + 2(wh).

Volume is expressed in cubic units.

You don't have enough information to do that, unless there is more to the problem that you aren't telling us. For example, if it says that the length equals x and the width equals 2x, you could use algebra to solve for x: Volume = (height)(x)(2x). Volume = (height)(2x^2). Volume/(2*height) = x^2. So x = square root of (volume/2*height), and the width is twice that.

Volume equals area multiplied by depth.

Multiply length by width. Divide that product into the volume.

One liter is equal to 1,000 cubic centimeters. So 800 liters are equal to 800,000 cubic centimeters. 800,000 ÷ 50 (the width) = 16,000. That means the length multiplied by the height is 16,000. So you're free to pick any numbers for the length and height, such that they multiply together to make 16,000, such as 200 cm and 800 cm.

For all prisms, the formula to find its volume is given by taking the area of the cross section multiplied by the uniform length, width or height. I am assuming the area of 3/20 you mentioned is the cross section area. Therefore, the volume is 3/20 times 2/3 = 1/10 (units).

When you double the length, breadth and height of a solid, the new volume doesn't actually double. It octuples because 2 cubed is 8.
