Answer:
110
Step-by-step explanation:
Formula for SA of a rectangular prism:
SA = 2lh + 2lw + 2wh
Given dimensions:
l = 1
w = 7
h = 6
Simply plug in these given dimensions into the SA formula to get the answer
SA = 2lh + 2lw + 2wh
Substitute given variables
SA = 2(1)(6) + 2(7)(1) + 2(6)(7)
* Multiply parentheses that are next to each other *
SA = 2(6) + 2(7) + 2(42)
* Multiply again *
SA = 12 + 14 + 84
*add*
SA = 110
