6 * 2.5 = 15 That’s the area of the base
2.5 * 4 = 10 
10 * 2 = 20
That’s the area of the 2 smaller sides
6 * 4 = 24 
24 * 2 = 48
That’s the area of the 2 larger sides
Then you add all the dimensions together.
15+20+48 = 83. 
So, the final equation is (6*2.5) + 2(2.5*4) + 2(6*4) = 83
        
             
        
        
        
Answer:
C) 8 and 9

We know that 70 is between two perfect squares.
The square numbers 64 and 81 can help us solve this question.
64<70<81
We take square root to get:

We simplify this to get:

Therefore √70 is between 8 and 9.
The correct option is C.

78×.33=25.74 busses are new
25.74+15=40.74 new busses
78+15=93 total busses
40.74/78=0.5223076923= 52% will be new with the new 15 busses
