tank has sides with lengths of 4.2 feet and 14.1 feet. If the height
of the tank is 9 feet, what is the total surface area of the tank?
A. 283.14 square feet
B. 329.4 square feet
C. 447.84 square feet
D. 532.98 square feet

Answer 1

Answer: C

Step-by-step explanation:

Formula for SA of a rectangular prism:
`SA = 2(lw + lh + wh)`

Plug in length, width, and height

`SA = 2((4.2)(14.1)+(4.2)(9)+(14.1)(9))`

`SA = 447.84` ft
