Question

What is the edge length of a 305-g iron cube? (The density of iron is 7.86 g/cm3g/cm3, and the volume of a cube is equal to the edge length cubed.

Answer 1

Answer: edge length = 3.61 cm

Step-by-step explanation:

Givens

m = 369 gm

d = 7.86 gm / cm^3

v = ?

Formula

v = m / d

Solution

v = 369 / 7.86

v = 46.95 cm^3

============

That's not the answer. You must take the cube root of the volume

side = cube root (46.95)

side = 3.61 cm
