or 5 lengths of 234 feet to be cut from a board, the board must have a length of at least 1170 feet.
Let x represent the total length of the board so as to allow for the cutting of 5 lengths.
Since each length needed to be cut is 234 feet, hence:
x = number of lengths × feet per board
x = 5 lengths × 234 feet
x = 1170 feet
Hence for 5 lengths of 234 feet to be cut from a board, the board must have a length of at least 1170 feet.

Explanation:
Answer:
2H2O
Explanation:
Given that,
H2SO4 2NaOH → Na2SO4
We know that,
The number of atoms of the reactant and the number of atoms of the product is equal in the reaction.
Therefore,
H2SO4 2NaOH → Na2SO4+2H2O
Hence, the additional product balances the reaction is 2H2O
Density = mass / volume
mass = 44 g
volume = 9 cm³
Density = 44 g / 9 cm³ ≈ 4.9 ≈ 5 g/cm³
