Find the surface area of the rectangular prism

22mi

Step-by-step explanation:

Formula: A=2(wl+hl+hw)

h=1mi

l=5mi

w=1mi

Using the formula,

2·(1·5+1·5+1·1)=22mi

Therefore, the surface area of the rectangular prism is 22mi

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.
