Answer 1

Rounding volume to nearest whole number is 5cm³.

Step-by-step 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.
