Triangular prism
length of slanted side:
sqrt(3^2 + 4^2) = 5
SA = 2(1/2)(8)(3) + 8(12) + 2(5)(12) =240
V = (1/2)(8)(3)(12) = 144
cuboid
SA = 2(7x6) + 2(7x5) + 2(6x5) = 214
V = 7x6x5 = 210
When you want to use a discount membership to save money you are required to purchase a membership. A popular place that people often purchase memberships from are Costco or Sam's Club.
First multiply 76 by 80/100
(76 x 80 )/100 = 60.8
Now because the price has to be reduced...
76 - 60.8 = $15.2
Hope this will help.
The answer is square root 6/2
