A box with a square base and open top must have a volume of 237276 cm^3. We wish to find the dimensions of the box that minimize

svp [43]

Answer:

$A(x)=\dfrac{x^3+949104}{x}$

Step-by-step explanation:

Given a box with a square base and an open top which must have a volume of 237276 cubic centimetre. We want to find a formula for the surface area of the box in terms of only x, the length of one side of the square base.

Let the side length of the base =x

Let the height of the box =h

Since the box has a square base

Volume,

$V=x^2h=237276\\\\h=\dfrac{237276}{x^2}$

Surface Area of the box = Base Area + Area of 4 sides

$Area, A(x,h)=x^2+4xh$

Substitute h derived above into A(x,h)

$Area=x^2+4x(\frac{237276}{x^2})\\\\A(x)=x^2+\dfrac{949104}{x}\\\\A(x)=\dfrac{x^3+949104}{x}$

Therefore, a formula for the surface area of the box in terms of only x, the length of one side of the square base is:

$A(x)=\dfrac{x^3+949104}{x}$

Please help! Measure of angles. Will award brainliest

klasskru [66]

Answer:

110 degrees, 84 degrees

Step-by-step explanation:

Picture 1:

See attached image for the angles I am referencing.

measure of angle a= measure of the 110 degree angle because of corresponding angles

measure of angle b=measure of angle a because of vertical angles

Therefore, through transitivity, we can state that the measure of

angle b= angle a= 110 degrees

Picture 2:

angle x=84 degree angle through alternate interior angles.
