Kevin is creating a target for a game that will be played at the school's carnival and needs to put red tape in the shape of an "x" as shown below. If the area of the square board is 25 square feet, how many feet of tape will he need?

Answers

Answer:Kevin need 14.14 feet of red tape

Step-by-step explanation:

Given: (Figure Attached)

Area of Square = 25 square feet

As we know

Area of square = length x width = a x a = 25

a * a = 25

a = ±5 by taking square root both sides

It means a = 5 as the length can not be negative

Now we know the length of sides of square and as shown in figure we can break the figure in two triangles,

By using Pythagoras theorem on one triangle we will find the length of one line of x and then multiply the x with 2 to get the overall feet of tape.

x = ± 7.07 It means x = 7.07

Now the total tape required is 2 * x = 2*7.07 = 14.14

A rectangular box is designed to have a square base and an open top. The volume is to be 2048in.3

What is the minimum surface area that such a box can have?

Answers

Answer:

x=y=z in 3 dimensions. So, you have x2y=4=x3⟹x=y=3√4.

Step-by-step explanation:

Answer:

Step-by-step explanation:

Let x = the length of the sides of the base and h = the height:

Volume = (area of base)(height)

V = x2h

2048 = x2h

2048/x2 = h

Surface Area = area of base + 4(area of vertical side)

SA = x2 + 4xh

Eliminate the h by using 2048/x2 = h:

SA = x2 + 4x(2048/x2)

SA = x2 + 8192 x-1

Take the derivative of SA wrt x, set it to zero, solve for x. Plug that value of x into the surface area equation to find the minimum surface area.
