The volume of a rectangular box is 5760 units^3
the surface area is 2002 units^2
The sum of the edges of the box sum up to 216 units
If the edges of the box are increased by 1 unit , work out the new volume of the box

Answers

The new volume after the edges of the box are increased by 1 unit = 266,491 units^3

Calculation of volume of rectangular box

The volume of a rectangle= l×w×h

The surface area of the box = (side)^2

The sum of the edges of the box = 216 units

If area of the box x^² = 2002

X = √2002

X = 44.7units

But the sum of the edges = 216 units

44.7 + 44.7 + y = 216

make y the subject of formula,

y = 216 - 89.4

y= 126.6 units

Therefore the length, width and height of the rectangular box = 44.7, 44.7 and 126.6 units respectively.

When additional 1 unit is added to each edge it becomes,

44.7 +1 =45.7,

44.7 + 1 = 45.7and

126.6 + 1 = 127.6 units.

Therefore the new volume = 45.7×45.7 × 127.6 = 266,491 units^3.

What is the exponent of log rule?

The exponent of the log rule says that the raising a logarithm with a number to its base is equal to the number.

For example, let k is the number and a is the base. Thus,

The logarithmic equation given in the problem is,

[tex]4^{\log_4(x+8)}=4^2[/tex]

The height of a trapezoid is 6 in. and its area is 72 inches squared. One base of the trapezoid is 6 inches longer than the other base. What are the LENGTHS of the bases?

Answers

Answer:

  9 and 15 inches

Step-by-step explanation:

The unknown lengths can be found by making use of the formula for the area of a trapezoid.

__

Let x represent the shorter base. Then the longer one is (x+6), and the area is ...

  A = 1/2(b1 +b2)h . . . . area of a trapezoid with bases b1, b2, and height h

  72 = 1/2(x +(x+6))(6)

  24 = 2x +6 . . . . . . . . .  simplify, divide by 3

  18 = 2x . . . . . . . . . subtract 6

  9 = x . . . . . . divide by 2

  15 = x+6 . . . . . . the length of the longer base

The bases are 9 inches and 15 inches in length.

A family-sized box of cereal with dimensions 3x9x12 inches costs $6, while the regular size with
dimensions 2 x 8 x 9 inches costs $4.50. What is the difference in price per cubic inch?

Answers

Cubic inch means we are dealing with volume.

So,

Calculate the volume of both boxes.

1. 3x9x12 = 324 cubic inches

2. 2x8x9 = 144 cubic inches

First box costs $6 for 324 cubic inches, so if you divide 6 by 324 you will get the price for 1 cubic inch of the box.

6/324 = $0.018518518518519

2.

Second box costs $4.50 for 144 cubic inches.

4.5/144 = $0.03125

Subtract the cheaper one from the more expensive one to find the difference.

0.03125 - 0.018518518518519 = 0.012731481481481

The difference in price per cubic inch is

$0.012731481481481

Sand is deposited into a pile with a circular base. The volume V of the pile is given by V - r^3/3. Where r is the radius of the base, in feet. The circumference of the base is increasing at a constant rate of 5. Fect per hour. When the circumference of the base is 8x feet, what is the rate of change of the volume of the pile, in cubic feet per hour?​

Answers

The rate of the change of the volume of the pile, in cubic feet per hour, when the circumference of the base is 8x feet, for this case, is 40x²/π³ cubic ft/ hour.

How to calculate the instantaneous rate of change of a function?

Suppose that a function is defined as;

[tex]y = f(x)[/tex]

Then, suppose that we want to know the instantaneous rate of the change of the function with respect to the change in x, then its instantaneous rate is given as:

[tex]\dfrac{dy}{dx} = \dfrac{d(f(x))}{dx}[/tex]

What is chain rule of differentiation?

If a variable z depends on the variable y, which itself depends on the variable x, then we have:

[tex]\dfrac{dz}{dx} = \dfrac{dz}{dy} \times \dfrac{dy}{dx}[/tex]

(assuming all these derivatives exist).

For this case, we're given that:

[tex]V = \dfrac{r^3}{3}[/tex]    (in cubic ft)

Assuming the cross section being circular, expressing radius 'r' in terms of circumference, we get:
[tex]C = 2\pi r\\\\r = \dfrac{C}{2\pi}\\\\V = r^3/3\\\\V = \dfrac{C^3}{24\pi^2} \: \rm ft^3[/tex]

It is given that rate of change of circumference with respect to time is 5.

Thus, symbolically, we get:
[tex]\dfrac{dC}{dt} = 5[/tex]

Finding rate of change of volume with respect to time:

[tex]\dfrac{dV}{dt} = \dfrac{d\left (\dfrac{C^3}{24\pi^2}\right) }{dC} \times \dfrac{dC}{dt} = \dfrac{3C^2}{24\pi^3} \dfrac{dC}{dt} = \dfrac{5C^2}{8\pi ^3} \: \rm ft^3/hour[/tex]

(using chain rule of differenciation).

At C = 8x ft, we get:
[tex]\dfrac{dV}{dt} = \dfrac{5C^2}{8\pi ^3} \: \text{ft}^3\text{/hour}\\\\\dfrac{dV}{dt} |_{C = 8x} = \dfrac{5(8x)^2}{8 \pi^3} = \dfrac{40x^2}{\pi^3} \: \rm ft^3/hour[/tex]

Thus, the rate of the change of the volume of the pile, in cubic feet per hour, when the circumference of the base is 8x feet, for this case, is 40x²/π³ cubic ft/ hour.
