Joy knits a square blanket that has an area of 1,500 square inches . What is the approximant length for each side of the blanket

Alex777 [14]

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.

Whats the surface area of this prism plz help.Urgent

Sergio039 [100]

Answer:

The surface area of a solid object is a measure of the total area that the surface of the object occupies. The mathematical definition of surface area in the presence of curved surfaces is considerably more involved than the definition of arc length of one-dimensional curves, or of the surface area for polyhedra (i.e., objects with flat polygonal faces), for which the surface area is the sum of the areas of its faces. Smooth surfaces, such as a sphere, are assigned surface area using their representation as parametric surfaces. This definition of surface area is based on methods of infinitesimal calculus and involves partial derivatives and double integration.
