surface area of a rectangular prisms i have one with the same # on each side how many times should i * it
To find the surface area of a rectangular prism, you need to multiply the length, width, and height of the prism by 2 and then add up the results.
If you have a rectangular prism where all sides have the same length, then you can simplify the calculation. Let's denote the length of the sides as "x".
The formula for the surface area of a rectangular prism is:
Surface Area = 2(length × width + length × height + width × height)
Since all sides have the same length (x), the formula can be further simplified:
Surface Area = 2(x × x + x × x + x × x)
Simplifying further:
Surface Area = 2(3x^2)
To calculate the surface area of the prism, you need to multiply 3x^2 by 2.
So, to answer your question, you need to multiply the value of 3x^2 by 2 to find the surface area of a rectangular prism where all sides have the same length.
