Answer:
The surface area of the box if it is scaled up by a factor of 10 is <u>7400 in²</u>.
Step-by-step explanation:
Given:
The surface area of the box is scaled up by a factor of 10.
Surface area is 74 in².
Now, to find the dilated surface area of the box.
As the figures are same of the box so the surface area of original box is equal to square of the dilated box.
So, let the surface area of the dilated box be .
Let the surface area of the original box be .
And let the scale factor be .
Thus,
By cross multiplication we get:
Therefore, the surface area of the box if it is scaled up by a factor of 10 is 7400 in².

The histogram will have a horizontal or an x axis of time/minute intervals of the calls (5 minutes in each), and the vertical axis or y axis will be the number of calls made.
Area for question 1 is the equation (HxB)÷2 or 1/2BxH (that is how you find the area of a triangle.
To work out the Perimeter of the triangle you need to work out the value of each outter side. to work this out you need to use the equation a²+b²=c² where the value of c is the longest side in the right-angled triangle
1A) 22.5 inch²
1P) 5²+4.5²=c² = 25+20.25=c² = 45.25=c²
c=√45.25 = 6.73(2DP). The perimeter of this triangle is Base+2C which is 9+(6.73x2) = 9+13.46=22.46 inch
2A) 11x12=132÷2=66 inch²
2P) 11+12+13=36 inches
