Answer:
You obviously copied the question text in an incomplete and lazy way.
I still really wanna help you on your problem.
Please either point the whole question with the possible answers or make a photograph of the problem.
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

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

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
Answer: a = 0.81
So yeah, that is the answer.
Answer:
C
Step-by-step explanation:
Graph C cause it gets multipled by 20 each time
You will need to use this formula:
Principal = Total ÷ (1 + Rate) ^ <span>years
</span><span>Principal = 35,000 / [1.08]^4
</span><span><span><span>Principal = 35,000 / 1.36048896
</span>
</span>
</span>
Principal =
<span>
<span>
<span>
25,726.04
</span>
</span>
</span>
So, you would have to deposit $25,762.04 @ 8 per cent to have 35,000 in four years.
