An open box with a square base is to be made from a square piece of cardboard 24 inches on a side by cutting out a square from e
laila [671]

Answer:

x=4 Inch

Step-by-step explanation:

Length of the Square = 24 Inches

If a Square of Length x cm is cut out from each corner

Length of the Box = 24-x-x=(24-2x) Inches

Width of the Box =24-x-x=(24-2x) Inches

Height of the box = x inches

Volume of a Cuboid = Length X Width X Height

V(x)= x(24-2x)(24-2x)

Simplifying

V(x)=4x(12-x)(12-x)

To determine the value of x at which V is largest, we take the derivative of V(x) and solve for the critical points.

V(x)=4x(12-x)(12-x)

V^{'}(x)=12(x-12)(x-4)

Set the derivative equal to zero to obtain the critical points

V^{'}(x)=12(x-12)(x-4)=0\\Since \: 12\neq 0\\(x-12)(x-4)=0\\x-12=0 \:or\: x-4=0\\x=12 \:or\: x=4

x cannot be equal to 12 as it divides the length of the square cardboard into exactly two equal parts.

When x=4

V(4)=4*4(12-4)(12-4)=16*8*8=1024 Cubic Inches

When x=4 Inch, the volume, V of the open box is largest.

What is the value of h?
storchak [24]

Answer:

\large\boxed{h=5.488\ in}

Step-by-step explanation:

The formula of an area of a parallelogram:

A=bh

b - base

h - height

We have:

base₁ = 9.8 in

base₂ = 10 in

height₁ = 5.6 in

height₂ = h

The area of a parallelogram:

A=b_1h_1 and A=b_2h_2

Therefore we have the equation:

b_2h_2=b_1h_1

Substitute:

10h=(9.8)(5.6)

10h=54.88          <em>divide both sides by 10</em>

h=5.488\ in
