Answer:

The volume of the room is 42336.

Step-by-step explanation:

Given,

Area of the floor = 112\ ft^2

Let the width of the room be x.

Since the length of the room is 2 feet more than twice the width.

\therefore\ length=2x+2

Since the room is rectangular, so we use the formula of area of rectangle.

Area = length\times width

On substituting the values, we get;

(2x+2)\times2=112\\\\4x+4=112\\\\4x=112-4\\\\4x=108\\\\x=\frac{108}{4}=27

Width = 27

Length = 2x+2=2\times27+2=54+2=56

The height is 1 foot greater than the width.

\therefore Heigth=27+1=28

Now,

Length = 56    Width = 27     Heigth = 28

And we know volume of a rectangular prism is length times width times height.

Volume =length\times width\times\ height.

Volume = 56\times27\times28= 42336\ ft^3

Thus the volume of the room is 42336.

Answer:

896

Step-by-step explanation:

112=(2w+2)W

W=7,-8 cant be negitive so 7

L=(7)2+(7)=16

H=7+1=8

V=7*16*8

V=896

Answer:

19.4in

Step-by-step explanation:

1) formula for area of a triangle:

(b*h)/2=a

the area and height are already given so lets substitute them in the formula.

(b*23.8)/2=230.86

1) multiply by 2 on both sides

b*23.8=461.72

divide by 23.8 on both sides

b=19.4

the base is 19.4 in

hope this helps

C^{2}  = 576 + 324

C^{2} = 900

C = \sqrt{900}

C = 30

Does that make sense?  :|
