Answer:
1) Option C - 39 inches
2) Option C - 12167 cubic feet
Step-by-step explanation:
1) Given : Joy knits a square blanket that has an area of 1,500 square inches
To find : What is the approximate length for each side of the blanket.
Solution: Area of square = 1500 square inches
Let the side of the blanket = s
Formula of area of square is ![A= s^2](https://tex.z-dn.net/?f=A%3D%20s%5E2)
![1500= s^2](https://tex.z-dn.net/?f=1500%3D%20s%5E2)
![s= \sqrt{1500}](https://tex.z-dn.net/?f=s%3D%20%5Csqrt%7B1500%7D)
![s=38.7](https://tex.z-dn.net/?f=s%3D38.7)
Approximately Side of blanket = 39 inches
Therefore, Option C is correct.
2) Given : Jeff is an architect and is drawing the plan for a room addition for a client. If the shape of the room is a cube.
To find : what is the volume in cubic feet if the length is 23 feet?
Solution: Length of side of a cube (a)= 23 feet
Let the volume of a cube = V
Formula of Volume of cube is ![V= a^3](https://tex.z-dn.net/?f=V%3D%20a%5E3)
![V= (23)^3](https://tex.z-dn.net/?f=V%3D%20%2823%29%5E3)
![V= 12167](https://tex.z-dn.net/?f=V%3D%2012167)
Volume of a cube = 12167 cubic feet
Therefore, Option C is correct.
