23.4. Doubling is twice the amount. So dividing 46.8 by 2 will give you the original number

Answer:
160
Step-by-step explanation:
Each cube is 1/2 inch, so there will be 2 cubes in each 1 inch of length. The dimensions of the prism in terms of the number of cubes are ...
length: 4 in ⇒ 4×2 = 8 cubes
width: 2 in ⇒ 2×2 = 4 cubes
height: 2 1/2 in ⇒ (2 1/2)×2 = 5 cubes
Then the number of cubes required to fill the prism is ...
8 × 4 × 5 = 160 . . . . cubes
The volume of the prism is equivalent to that of 160 1/2-inch cubes.
L = 2w + 4 , l + w = 80
solve using subsitiution.
(2w + 4) + w = 80
simplify / combine common
3w + 4 = 80
subtract 4 from both sides
3w = 76
divide by 3
w = 25 1/3 in
80 - 25 1/3 = 54 2/3
is it true that 54 and 2/3 inches is 4 inches more than two times 25 1/3? Yes.
Length = 54 and 2/3 inches
W = 25 and 1/3 inches
hope this helps ;D
