Answer:
Volume: 112 m³.
Surface area: 172 m².
Step-by-step explanation:
The volume is the base times height times length. So, the volume will be 2 * 8 * 7 = 16 * 7 = 112 m³.
The surface area is 2lw + 2lh + 2wh. l = 8; w = 7; h = 2.
2(8)(7) + 2(8)(2) + 2(7)(2) = 2 * 56 + 2 * 16 + 2 * 14 = 112 + 32 + 28 = 112 + 60 = 172 m².

B
Step-by-step explanation:
Answer: 348.8 miles on 16 gallons of gas
Step-by-step explanation:
Make the following proportion:
= ![\frac{x miles}{16 gallons}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%20miles%7D%7B16%20gallons%7D)
Since the car consumes gas at the same rate and only the amount of gas is changed, these two fractions must be equivalent. If the rate at which the car consumes gas changes, it would be different.
Use basic algebraic skills and you should get 348.8 miles.
