The approximate side length of a square on the quilt = 6.32 inch
In this question,
Taynia makes a quilt using fabric squares.
We have been given the side length of each fabric square is the square root of the area.
Here, the area of each fabric square is 40 square inches.
We need to find the approximate side length of a square on the quilt.
Let A be the area.
A = 40 square inches
To find the side length, we need to take the square root of 40.
Let s be the side length.
⇒ s = √A
⇒ s = √40
⇒ s = 6.32 inch
Therefore, the approximate side length of a square on the quilt = 6.32 inch

Answer:
-4
Step-by-step explanation:
v = 3(-1)-1 plug in -1 for r and multiply it by 3
v = -3-1 then combine like terms
v = -4
Assuming it is a right rectangular prism, the volume is 126 sq. in.
V = area of base * height = 18 * 7 = 126
