Answer:
What are you asking? If you're asking for the area of the prism, it's <em>774in²</em>.
Step-by-step explanation:
First you need to use this formula.
2(wl + hl + hw)
w = width
l = length
h = height
Since we already know what all of those values are, we don't need to do any solving for them.
In this case:
width = 9
length = 9
height = 17
Plug those numbers into the formula and solve.
2(9 × 9 + 17 × 9 + 17 × 9)
It would be easiest to multiply the numbers before doing your adding.
2(81 + 153 + 153)
Add.
2(387)
Multiply what is in the parenthesis with the number on the outside, 2.
There's your answer, <em><u>774</u></em>.
Since this is area, you have to specify the type of measuring you're using (example: inches, feet, yards) and you have to be sure to include the ² after the measurement you're using because you may get points off for that.
<u>774in²</u>

Answer:
3.79 miles per hour to the nearest hundredth.
Step-by-step explanation:
There are 3600 seconds in 1 hour.
50 feet in 9 seconds = 50/9 feet per second.
= (50/9) * 3600 feet per hour
= (50/9) * 3600 / 5280 miles per hour.
= 50 * 400 / 5280
= 3.79 miles / hour.
