Calculating Total area of cubes |
 Imagine a box, every side that is visible to you has another side that is exactly the same behind it. In other words, the top has the exact same measurements as the bottom, each of the sides are exactly the same as the side on the opposite end. Thus calculating the total area of such a figure involves calculating the area of each visible side, sum them up and then multiply your result by 2. For example surface Areas of the faces in the figure above: Area A = l x b = 2cm x 4cm = 8cm2 Area B = l x b = 6cm x 2cm = 12cm2 Area C = l x b = 6cm x 4cm = 24cm2 Now that we have the surface areas of each vissible side, we can now add them up and then multiply our result by 2. Total area = 2(Area A + Area B + Area C) = 2(8 + 12 + 24) = 2(44) =88cm2 |
