Step-by-step explanation:
To find the surface area of a rectangular prism such as this, is basically just like finding the OUTSIDE surfaces. We are looking for the "perimeter" of a 3D shape.
How do we do it?
- Calculate each face of the prism by multiplying Length x Width.
- Make a shortcut by combining like-figures (front of the cube and back of the cube are the same surface areas, etc.)
- Make your formula
- 2(4 · 15) + 2(10 · 15) + 2(12 · 4)
You have to set up to equations
EQ 1: x-2=2 EQ 2: x+2=2
Solve for x and see which value fits the conditions, in this case 4
Answer:
60
Step-by-step explanation:
There are 2+5 = 7 ratio units of students. If we multiply the numbers by 5, we can have a total of 35 ratio units of students: 10 : 25.
Now, we can substitute this into the ratio of teachers to students:
teachers : students = 3 : 35
teachers : (male students : female students) = 3 : (10 : 25)
Then the number of teachers is seen to be 3/25 of the number of female students:
(3/25)(500) = 60 . . . teachers
