Draw a right rectangular prism. Draw it so one face is pretty much the way you would see it if it was real. The other two faces you can see have a slant to them.

Label the face you can see as x and y. Name any of the slanted lines as z. Put cm for centimeters behind the letters.

Volume = x*y*z the units here are cm^3
Why because you are multiplying cm*cm*cm together.

The surface area is a whole different ball game.
you have 2 surfaces who have areas of x*y There's one in front of you and one you cannot see
You have a top and a bottom that is y*z each that's 2y*z

You have two surfaces that are x*z each and that's 2x*z

The total surface area = 2xy + 2xz + 2yz
The units here are cm*cm or cm^2

Find the midpoint of segment JT when the coordinates are J(-3,18) and T(7,-10). Show all work
nignag [31]
Given two points (x₁,y₁) and (x₂,y₂), the midpoint of the segment will be:
( (x₁+x₂) / 2 , (y₁+y₂)/2  ).
In this case:
J(-3,18)
T(7,-10)

The midpoint will be:
( (-3+7)/2  ,  (18-10)/2 )=(4/2 , 8/2)=(2, 4).

Answer: the midpoint of segment JT is (2,4)
