To solve this, we must know the formula for surface area of a rectangular prism. The formula solves for 3 of the faces, and then multiplies by 2, because in a rectangular prism, 2 opposite sides will always be equal.
The formula is 2(wl+hl+hw)
Now all we have to do is substitute in our values and solve.
2(wl+hl+hw)=
2(12*11+11*11+11*12)=
2(385)=
770=
Using the math above, we can see that the correct answer is A. 770 square cm.
Answer:
3
Step-by-step explanation:
In order to do this, you have to use the Pythagorean Theorem which is a^2 +b^2=c^2 It does not matter in what order a and b are, but c is always the hypotenuse or the side across from the right angle. First, you substitute 24 in for a and 45 in for b so your equation so far would look like 24^2 + 45^2 = c^2 Then, you square 24 and 45 and get 576+2025=c^2 Then you add the two to get 2601=c^2 Finally, you would square root both sides and get 51=c So the width of the recycling bin is 51 inches long
Answer:
4 minutes is the answer ok
Hello!
Since the shape has 6 points it is a hexagon
The sum of the angles in a hexagon add to 720
You add all the angles you know
102 + 133 + 117 + 170 + 90 = 612
Subtract this from 720 to find b
720 - 612 = 108
The answer is B) 108°
Hope this helps!
