The surface area of a rectangular prism needs an formula.
For a rectangular prism you have to understand some about the shape.
It is a 3D shape consisting of 6 sides
all are rectangles
to determine the area of one rectangle is the base multiplied by the height or in this case length times with.
but you also need to account for all sides and the height.
so the Surface area formula would be like
sa = l \times w + l \times h + w \times h
this accounts for 3 of the sides of the rectangular prism.
the top,bottom,and side.
so to get the surface area of a rectangle prism you must mutiply each side by 2 to account for all sides of the rectangular prism.
so the surface area formula for a rectangular prism is
SA = 2\\  \times l \times w +2 \times l \times h+2 \times h \times w
I won't solve it for you but just plug in your values for l,w,and h into that formula and you will get your answer in metres squared or m

Determine if the following relations are functions. If they are functions, also state the domain and range.
Zigmanuir [339]

Answer:

No it is not a function because the 10 in the input is repeated twice (the arrow is connected to 2 numbers)

D= {7, 9, 10}

R= {7, 9, 8, 10}

The pairs are (7, 7), (9, 9), (10, 8), (10, 10)

Step-by-step explanation:

Hi

when t = 0 then s (t) = 1/4

when t tends to infinity then s (t) tends to 0

when t tends to infinity then s (t) tends to infinity

the function has a horizontal asymptote at y = 0
