Answer:

Length = 9 cm

Weight = 6 cm

Height = 3 cm

Step-by-step explanation:

Given the height of rectangular piece = [tex]x[/tex] cm

Length = 3 times the height = [tex]3x[/tex]

Width = 2 times the height = [tex]2x[/tex]

Volume of rectangular piece = 162 cubic cm

Let us have a look at the formula for volume of a rectangular shape 3D sculpture i.e. a Cuboid.

Volume = Length [tex]\times[/tex] Width [tex]\times[/tex] Height

Putting all the given values:

[tex]162=3x\times 2x\times x\\\Rightarrow 6x^3=162\\\Rightarrow x^3=\dfrac{162}{6}\\\Rightarrow x^3 =27\\\Rightarrow \bold{x =3 \ cm}[/tex]

Therefore, the answer is:

Length = 3 [tex]\times[/tex] 3 = 9 cm

Width = 3 [tex]\times[/tex] 2 = 6 cm

Height = 3 cm
