A cardboard box is shaped like a cube. The length of each side is 15 inches.
What is the surface area of the box, in square inches?
Work Shown:
s = side length = 15 inches
SA = surface area of the cube
SA = 6s^2
SA = 6*15^2
SA = 6*225
SA = 1350
The surface area is 1350 square inches.
Note the formula has us compute the area of each square face, which is s*s = s^2. Then we multiply by 6 since there are 6 identical square faces on the cube.
Answer:
1350 [tex]in^{2}[/tex]
Step-by-step explanation:
A cube has six sides. To find the area of a square, multiply the length by itself:
15 x 15 = 225
Since each side is the same (because the box is a cube), simply multiply 225 by 6 (the number of sides on a cube):
225 x 6 = 1350
What is the density of an object that has a mass of 20 grams and has a length of 8cm and a width of 2cm and a height of 5cm????
Answer:
Volume is the amount of space an object occupies. To determine the volume of any rectangular object, multiply the measurements of length, width, and height.
Volume = Length × Width × Height
Calculate the volume of this rectangular object.
Length = 3 cm
Width = 3 cm
Height = 12 cm
Volume = l × w × h
Volume = 3 cm × 3 cm × 12 cm
Volume = 108 cm3
Notice that the units for volume are cubic centimeters (cm3).
So 8 ÷ 25 = 0.32 and the units would be g/ cm3 . Other units of density could be g/L or g/ml or mg/ cm3 or kg/ m3 and the list could go on and on. Any unit of mass divided by any unit of volume.

Answer:
234Step-by-step explanation:
surface area = 2( LW + LH + WH)
where L = Length = 9
W = Width = 2
H = Height = 9
plugin values into the formula:
surface area = 2 ( LW + LH + WH)
= 2 ( 9*2 + 9*9 + 2*9 )
= 2 ( 18 + 81 + 18 )
= 2 (117)
= 234

What number must be placed in the box in the equation below to produce an equation that has more than one solution: 5u+3(4u-6)=-3u-27+20u+ ▢
Answer: the number must be placed in the box is 9
suppose: the number must be placed in the box is x
have:
5u + 3(4u - 6) = -3u -27 + 20u + x
⇔ 5u + 12u - 18 = -3u - 27 + 20u +x
⇔ 17u + 3u - 20u = -27 + 18 + x
⇔ 0 = x - 9
⇔ x = 9
Step-by-step explanation:
Answer:
9
Step-by-step explanation:
Simplifying both sides gives
17u - 18 = 17u - 27 + ▢.
Subtracting 17u from both sides gives
-18 = -27 + ▢.
If the number in the box is anything but 9, then the equation cannot be true, and the original equation has no solutions. If the number in the box is 9, then the two sides of the original equation are equivalent, and all values of u are solutions to the equation.

Shean has a piece of string 7/8 meter long. He uses 1/5 of he piece of string to tie a package and cuts the rest into 5 equal parts. What is the length of the pieces.
Answer:
7/50 meter
Step-by-step explanation:
Total piece of string = 7/8 meter
Used string = 1/5 of the piece of string
Used string =
1/5 of 7/8 meter
= 1/5 × 7/8
= 7/40 meter
Balance = Total string - used string
= 7/8 - 7/40
= 35-7/40
= 28/40
Balance = 28/40 meter
cuts the rest into 5 equal parts. What is the length of the pieces.
28/40 ÷ 5
= 28/40 × 1/5
= 28 / 200
= 7/50 meter
Length of each piece = 7/50 meter

Peter shot 40 free throws. He made 80% of his shots. What fraction is equivalent to 80%? Pleas answer im trying to get my work done over here. Im in math honors and im really not feeling it today so someone please!
Answer:
32 free throws.
Step-by-step explanation:
It is given that,
Peter shot 40 free throws. He made 80% of his shots.
We need to find the fraction that is equivalent to 80%.
It means we have to find 80% of 40. It can be calculated as follows :
[tex]F=\dfrac{80}{100}\times 40\\\\=32[/tex]
80% of 40 is equivalent to 32 free throws.
If 260 is 20% what is the number for 80%

an architect is designing a commemorative steel arch in the shape of a parabola. its axis is vertical and its feet are 300 yd. apart. If the focus of the parabolic arch is to be 80 yd. above the ground, how high must the arch be?
Answer:
125yd
option b is correct
The height of the arch from the ground will be 125 yards.
Given information:
An architect is designing a commemorative steel arch in the shape of a parabola.
Parabola is vertically placed and its legs are 300 yards apart.
The focus of the parabola is 80 yards above the ground.
Let a be the distance of focus from the vertex of the parabolic arch.
So, the equation of parabola will be,
[tex]x^2=-4ay[/tex]
Assume the origin is placed on the vertex of the parabola.
So, the coordinates of the legs will be,
(-150, -(80+a)) and (150, -(80+a))
Satisfy the above point with the equation of parabola as,
[tex]x^2=-4ay\\150^2=4a(80+a)\\a^2+80a-5625=0[/tex]
Solve the above quadratic equation as,
[tex]x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}\\a=\dfrac{-80\pm\sqrt{80^2+4\times 1\times5625}}{2}\\a=\dfrac{-80\pm170}{2}\\a=-125, 45[/tex]
The value of a can't be negative. So, [tex]a=45[/tex].
So, the height of arch will be,
[tex]80+a=80+45\\=125\rm\;yd[/tex]
Therefore, the height of the arch from the ground will be 125 yards.

Brady went on a field trip to the water park. The cost of the trip was $19.99 to get into the park. He bought a hot dog for $3.50 and spent $2.10 on gas money. How much money did Brady spend?
Given:
Cost of the trip to get into the park = $19.99
Brady bought a hot dog for $3.50 and spent $2.10 on gas money.
To find:
The total money Brady spend.
Solution:
It is clear that,
Total money he spend = Cost of the trip to get into the park + Cost of a hot dog + Amount he spent on gas money
On substituting the values, we get
Total money he spend = $19.99 + $3.50 + $2.10
= $25.59
Therefore, the total money Brady spend is $25.59.
