Answer:
Rounding volume to nearest whole number is 5cm³.
Explanation:
Given data:
Mass of smaller iron cube = 20 g
Density of cube = 7.87 g/cm³
Volume of larger cube = ?
Solution:
The mass of larger iron is twice of smaller iron cube.
It will be 40 g.
Now we will apply the density formula.
d = m/v
7.87 g/cm³ = 40 g/ v
v = 40 g/ 7.87 g/cm³
v = 5.08 cm³
Rounding answer to nearest whole number is 5cm³.
