Question

one component of a metal sculpture consists of a solid cube with an edge of length 38.1 cm . the alloy used to make the cube has a density of 7150 kg/m3 . find the cube's mass.

Answer 1

395.4 kg

Step-by-step explanation:

d = m/v

m = dv

First find vol. of the cube:

38.1 cm = 0.381 m

V = (.381 m)³ = 0.0553 m³

Now find the mass:

m = (7150 kg/m³)(0.0553 m³) = 395.4 kg
