How many corners does a cuboid have?

A cuboid, or right-angled prism, has eight corners. It is box-shaped with six flat rectangular sides that face each other and are connected at right angles.

If all the sides of a cuboid are the same length, it is a "cube." To find the volume of a cuboid, multiply the measurements of its length, width and height. To determine the total surface area of a cuboid, multiply the length of each dimension by each of the others, and then add the products together. Finally, multiply the total by two. For instance, if length equals seven, width equals five and height equals three, the equation is 2(7 x 5 + 5 x 3 + 7 x 3) = 142.
