Answer:
$62.1
Step-by-step explanation:
The tube of toothpaste shown cost $3.45. Estimate the price per cubic inch of toothpaste.
= Volume = Length × Width × Height
= 8 in × 1.5 in × 1.5 in
= 18 in³
From the above question:
1 in³ = $3.45
18 in³ = $x
Cross Mulitiply
x × 1 in³ = 18 in³ × $3.45
x = 18 in³ × $3.45/ 1 in³
x = $62.1
Therefore, the price per cubic inch of toothpaste is $62.1
