Since it is a rectangular prism, the front and back are the same. the sides are the same and the top and bottom are the same. You would find the area of the front and back first. Since they both have the same measurements, you can find the area of one of the faces and multiply by 2.
A=BH
A= 3x5
A=15
15x2=30
So the front and back's area is 30. Now you find the area of both sides. They are both rectangle so the formula is A=BH.
A=BH
A=3x5
A=15
15x2=30
Now you find the area of the top and bottom. It is also a rectangle so you will use the same formula.
A=BH
A=3x3
A=9
9x2=18
Finally, you add all these measurements together adn that is the surface area.
This surface area of this rectangle prism is 78.
$7.65 × 23 = $175.95
Answer: $175.95
What do you neeeeeed help onnn i got youuuuu just tell meeeeeee
ANSWER
The correct choice is C.
EXPLANATION
The perimeter of a rectangle is given by;
P=2(w+l)
For the first rectangle, the perimeter is;
P=2(8+4)=24
For the second rectangle, the perimeter is
P=2(8+8)=32
For the third rectangle, the perimeter is
P=2(8+12)=40
The correct choice is C
Answer:
The graph shows a relation and a function
Step-by-step explanation:
Because there is one value of y for every value of x, this is a relation and a function.
