Hello!
To find the surface area of a rectangular prism you use the equation
SA = 2(wl + wh + lh)
SA is surface area
w is width
l is length
h is height
Put in the values you know
SA = 2(4.5 * 16 + 4.5 * 29 + 16 * 29)
Multiply
SA = 2(72 + 130.5 + 464)
Add
SA = 2(666.5)
Multiply
SA = 1333
The answer is 1333 cm squared
Hope this helps!
Answer:
The one furthest to the right.
30 because teeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee
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
