Scale factor of area is the square of the scale factor of length
The required values are;
- The length of one sides of the garage was originally approximately <u>19.2 ft.</u>
- The length of one of the sides of the garage is now approximately <u>23.6 feet</u> long
- The percentage increase in length is approximately <u>22.5 %</u>
Reason:
The given parameters are;
The area of the square garage = 370 ft.²
The area of the new garage has 50% more space
Required;
Part A
The initial side length
The initial side length, given to the nearest tenth, <em>s</em>, is the square root of the area, <em>A</em>, given as follows;
- s = √(370 ft.²) ≈ 19.2 ft.
Part B
The side was increased by 50%, to give,
370 + 0.5×370 = 555
The new area of the garage = 555 ft.²
The side length of the new garage, s = √(555) ≈ 23.6
- The side of the garage now is 23.6 ft.
Part C
The percentage increase is given as follows;
- The percentage increase in length of the side of the garage is approximately 22.5 %

Answer:
1279.3 cubic inches (Rounded to the nearest tenth)
Step-by-step explanation:
Side of a cubic box = 12 inches
volume of cubic box = (since side is equal to 12 inches)
= = 1,728 cubic inches
It means that box can be filled with 1,728 cubic inches of any material
____________________________________________________
But, it is given that it has one basketball placed in it.
hence we need to find the volume of basketball .
Since basket ball is spherical in shape
formula to calculate its volume will be same as that of formula to calculate volume of sphere
volume of sphere = where r is the radius of sphere
radius of basketball = diameter/2 = 9.5/2 in = 4.75 inches
therefore volume of basket ball is given by
volume of basketball =
___________________________________________
In box with volume 1,728 cubic inches,, 448.693 cubic inches is occupied by basketball.
It means rest is empty which can be filled with foam.
To calculate the empty space, we subtract volume of basket ball from volume of box
volume of empty space = volume of box - volume of basket
= 1728 - 448.693 = 1279.307 cubic inches
1279.307 cubic inches in nearest tenth will be 1279.3 cubic inches.
Hence, 1279.3 cubic inches of foam are needed to fill the rest of the box
