Area = Length * Breadth.
area of an box is length x width.
You cut the shape down into smaller shapes that you recognise and know how to calculate the area of. Then calculate the area of the small shapes and add the all up.
Oh, dude, it's like super simple. So, to find the area of a rectangular prism, you just need to calculate the total surface area by adding up the areas of all the individual faces. It's like, you find the area of the base (length x width) and then multiply it by the height of the prism. Voilà, you've got the area of a rectangular prism!
This will usually be the case for objects that have different shapes: even if they have the same volume, it is unlikely that they have the same surface area. As an example, calculate the volume and surface area of the following two rectangular block shapes: 1) A 2 x 2 x 2 rectangular block 2) A 1 x 1 x 8 rectangular block
Area = Length * Breadth.
To calculate the cross sectional area of a rectangular tube, multiply the widths of two adjacent sides of the tube.
Surface area = 2ab + 2bc + 2ac
If the room is rectangular, the area is the product of its length and width.
area of an box is length x width.
Lol at your life
Formula: S = 2B + L
The same as you would calculate any other area. For example, if the base happens to be rectangular, you multiply length x width.
You cut the shape down into smaller shapes that you recognise and know how to calculate the area of. Then calculate the area of the small shapes and add the all up.
It is 2*(Length*Breadth + Breadth*Height + Height*Length).
To calculate the area of a rectangular block, you need to multiply its length by its width. The formula for the area of a rectangle is A = l x w, where A represents the area, l is the length, and w is the width. Simply plug in the values for length and width into the formula and perform the multiplication to find the area of the rectangular block.
You need to measure it. You cannot calculate it from the available information.
