Cuboid Surface Area Calculator

Are you at a loss as to how to calculate the surface area of a cuboid? Our cuboid surface area calculator will help you to sort out any questions or doubts you may have quickly and easily. Keep reading to learn:

• The meaning of cuboid;
• How many vertices a cuboid has;
• How to use our surface area of a cuboid calculator;
• The surface area of a cuboid formula; and
• How to find the surface area of a cuboid manually.

A cuboid is a solid convex shape with each of its six faces shaped like a rectangle. It is also known as a rectangular prism. Some good real-world examples of cuboids are:

• A book;
• A mattress; and
• A brick.

A cuboid has eight vertices. The vertices of a cuboid all form angles of 90 degrees.

To use the surface area of a cuboid calculator, enter the following:

• Length
• Width; and
• Height of the cuboid.

Our calculator will immediately return the total surface area of the solid.

Keep in mind you can use any units you wish - our tool will deal with it.

To find the surface area of the cuboid(s), you first need to:

1. Know the length (l), width (w), and height (h) of the shape.
2. Use the surface area of a cuboid formula:

3. Substitute the values for length, width and height - say 10, 7, and 8 cm, respectively. Then solve the equation

4. Then solve the equation:

Let's assume that the surface area, height, and width are 288, 4, and 6 cm, respectively. Here is what we do:

1. Use the surface area formula:
   s = 2(l×w + w×h + l×h) sq units.
2. Make l the subject of the formula:
   l = (s/2 - wh)/(w+h) units.
3. Substitute the values:
   = (288/2 - 6 × 4)/(4+6) cm.
4. Solve
   =( (144 - 24) / 10) cm.
   =120/10 cm.
   =12 cm.
