The surface area and volume for shapes

Now you may be wondering why do we have to find surface areas or volume for shapes, how is this going to apply to our daily life? Well it is useful for buildings, making pottery, architecture and etc… So I will try to teach you what I learned.
Each shape has it’s own formula, since they have different formulas you may confuse them with each other so it is better to memorize them. We will only talk about the surface area and the volume of a rectangular prism, since its a little difficult to talk about all the shapes each.

When answering a surface area question don’t forget to square the answer, finding the surface area of a rectangular prism is like finding the area outside a box. So we are given the Base, the Length and the height, So 2bh means 2 times base times height and it goes the same as the others, then you finally plus them together and thats your answer.

Now for volume is a little more simpler, its just base times height times length for the volume of the rectangle. But this time when writing your answer don’t forget to cube the answer, which means you have to put the number 3 instead of 2. Finding the volume is like finding how much can fit inside a box instead of the outside which is just the opposite.

For me to make this easier i just use the same numbers as the last rectangle, although it may have the same numbers the answrd will be very different, take a look here, when we just multiply them altogether we have a different answer. So don’t confuse surface area and volume, because it could lead to some accidents when working on a project, so we have to double check.
