What is a cuboid?A cuboid is a three-dimensional closed figure which has volume along with surface area.
The volume of a cuboid is the product of its length, width, and height.
The total surface area of a cuboid is 2(lw + wh + wl) and the lateral surface area is 2(l + w)×h.
Given, A box that has a volume of 729 inches.
First we'll prime factorize 729.
729 = 3×243 = 3×3×81 = 3×3×3×3×3×3.
If we take the cube root of 729 it would be 3×3 = 9.
So, It is a cube with a side length 9.
Now, We know area of a cube is side².
Therefore, The area of this cube is 9² = 81 in².

Randy was paid $50 for his first night in the restaurant where he works as a cashier. he worked the rest of the week for $6.50 per hour. the equation, y = 6.50x + 50, represents the amount he made that week. What are the ordered pairs for the equation when you use these x-values: 10 and 20
Step-by-step explanation:
so, we first put 10 in for x :
y = 6.50×10 + 50 = 65 + 50 = $115
and then we put 20 in for x :
y = 6.50×20 + 50 = 130 + 50 = $180
so, the ordered pairs are
(10, 115) and (20, 180)

How many solutions exist for the given equation?3x + 13 = 3(x + 6) + 1
Answer:
0
Step-by-step explanation:
3x+13=3(x+6)+1
Expand:
3x+13=3x+18+1
Simplify:
3x+13=3x+19
Subtract 13 from both sides:
3x+13-13=3x+19-13
Simplify:
3x=3x+6
Subtract 3x from both sides:
3x-3x=3x-3x+6
0=6
Since the sides are not equal there are no solutions to this problem

Answer:
if m∠1 = 30° then m∠3 = 30° as they are parallel to each other and that is why they will have same angles.
therefore m∠3 = 30°
extra's:
→ m∠2 = m∠4 =
→ (360-30*20)/2
→ 150°
...............................
See here
m<1 and m<3 are opposite angles to eachother.
And we know that opposite angles are equal
so
m<1=m<3 m<3=30°The question is in the picture please give me all the answers

A rectangle has length 14 cm and width 4cm what is the area of a square that has the same perimeter as the rectangle?
DUE IN 5 MIN!!!!! I GIVE BRAINLIEST!!!!!!! AND I GIVE POINTS IF U WANT!!!!!
Answer:
Given in the attachmentStep-by-step explanation:
Hope this helps ^^"
Answer:
81 cm²
Step-by-step explanation:
Start by finding the perimeter of a rectangle.
[tex]Perimeter = 2(l+w)[/tex]
Plug in the given values into the equation:
[tex]Perimeter=2(14+4)=2(18)=36\ cm[/tex]
Since the perimeter of a square is:
[tex]Perimeter = 4s[/tex]
We can plug 36 cm in for the perimeter to solve for s
[tex]36\ cm=4s[/tex]
Divide both sides by 4
[tex]s=9\ cm[/tex]
The area of a square is:
[tex]Area=s^2[/tex]
Plug in the 9 cm for s
[tex]Area=9^2=81 \ cm^2[/tex]
Grace got a haircut for $26.95, bought three shirts on sale for $18.50 each and a pair of jeans for $48, and purchased two CDs for $18.50 each. Round each amount to the nearest ten dollars to find a reasonable estimate of how much Grace spent.
26.95 + 18.5 * 3 + 48 + 18.5 * 2
18.5 * 3 = 55.5
18.5 * 2 = 37
37 + 55.5 + 48 + 26.95 = 167.45
= $167.5

Answer:
2nd number line represents √7 best
Step-by-step explanation:
Method 1
√7 ≈ 2.65
Therefore, the 2nd number line represents √7 best
(the one with the dot between 2 and 3)
Method 2
√1 = 1
√4 = 2
√9 = 3
Therefore, as √7 is between √4 and √9, the solution is somewhere between 2 and 3.
