Answer 1

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 $A= s^2$

$1500= s^2$

$s= \sqrt{1500}$

$s=38.7$

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 $V= a^3$

$V= (23)^3$

$V= 12167$

Volume of a cube = 12167 cubic feet

Therefore, Option C is correct.
