Surface area of the rectangular prism = 2(LW + LH + WH)
Where,
Length (L) = 16 in.
Width (W) = 5 in.
Height (H) = 12 in.
Substitute the values
Surface area of the rectangular prism = 2(16*5 + 16*12 + 5*12)
= 2(80 + 192 + 60)
= 2(332)
= 664 in.²
Answer from: Quest
it's equivalent, so we can say that its equal.
let's call the denominator x and the numerador is 18 less then denominator, x - 18.
multiply
2.x = 5.(x - 18)
2x = 5x - 90
90 = 5x - 2x
90 = 3x
x = 90/3
x = 30
so:

answer: 42
use a calculator to find that 845/73 = 11.575
the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.
subtract that result from 845 to get 845 - 803 = 42
