this is so you can find that once divided
120 ÷8 = 15
therefore n= 15
8×15 = 120
sorry if it's not too clear
The surface area (S) of a rectangular prism is given in terms of its length (L), width (W), and height (H) as
... S = 2(LW +WH + LH)
Substitute your numbers and do the arithmetic.
... S = 2(7.2·10 + 10·6.3 + 7.2·6.3)
... = 2(72 + 63 + 45.36)
... = 2·180.36
... = 360.72 . . . . square inches
I'm almost positive that the answer is 60 miles an hour but if I'm wrong I'm sorry. I think it's 60 cause in 4 hours they drove 240 miles and 240 divided by 40 is 60
80 * 25 /100 = 20 .........
