How would you work out the total surface area of a cube or a cuboid?

Answer 1

It dependsThat depends upon the shape of the object. Formulas for certain regular shapes are known. For example, the volume of a sphere, cylinder, cone, or cube can be easily determined from its dimensions. For irregular shapes, however, you have to submerge them in water and measure the amount of water they displace.

Answer 2

The cube is a special case of the cuboid (where length = breadth = height), so we will only consider the total surface area of a cuboid.

Let the cuboid have length l, breadth b and height h.

Then the surface area of the cuboid consists of 2 l x b rectangles, 2 b x h rectangles, and 2 l x h rectangles.

As such, the total surface area is 2bl + 2bh + 2lh = 2(bl + bh + lh).

Answer 3

To find the area of your rectangle, you multiply length x width. There is no volume to a rectangle that I know of. :-)

Answer 4

Multiply each of the dimensions together: height times width times depth. their product, including units, is the volume.

Answer 5

The answer depends on what information you do have about the cuboid.

For example, height = sqrt(principal diagonal squared - base diagonal squared)

Answer 6

What is the formula of height of cuboid
