The side of a solid metallic cube is 50 cm. It is melted and recast into 8000 similar solid cubical dice. Find the side of each die.
Answer & explanation
Correct answer: option 1
The side of the given metallic cube = 50 cm its volume = (50)3 cm3 = 125000 cm3
Let x' cm be the side of a cubical die. Then volume of 8000 dice = 8000 × (x)3 cm3
According to the problem, the volume of 8000 cubical dice = The volume of the given solid metallic cube
⇒ 8000 × (x)3 = 125000
$⇒x=\frac{5}{2}=2.5$
Hence, the side of the cubical die is 2.5 cm
