\bf \textit{the volume of one small cube is }V=\left( \frac{1}{2} \right)\left( \frac{1}{2} \right)\left( \frac{1}{2} \right)\implies V=\cfrac{1}{8}
\\\\\\
\textit{now, the box fits in }128\frac{1}{8}\textit{ of those cubes, thus its volume is}
\\\\\\
128\frac{1}{8}\cdot \cfrac{1}{8}\implies \cfrac{128\cdot 8+1}{8}\cdot \cfrac{1}{8}\implies \cfrac{1025}{8}\cdot \cfrac{1}{8}\implies \cfrac{1025}{64}\implies 16\frac{1}{64}~in^3

Tell me all the properties of algebra
Keith_Richards [23]

Answer:

  • Commutative Property of Addition.-  
  • 2 + 3 = 3 + 2
  •  Commutative Property of Multiplication.- ex. 5 × 7 = 7 × 5  
  • Associative Property of Addition.- ex.(2 + 3) + 6 = 2 + (3 + 6)  
  • Associative Property of Multiplication.- ex. (7 × 3) × 10 = 7 × (3 × 10)
  • Distributive Properties of Addition Over Multiplication- ex. 2 × (2 + 8) = 2 × 2 + 2 × 8  
  • (2 + 8) × 10 = 2 × 10 + 8 × 10
  • The reciprocal of a non zero real number a is 1/a.- ex. reciprocal of 5 is 1/5 and 5 × (1/5) = 1
