1) write down a different ratio equivalent to 12 : 3
2) write down a different ratio equivalent to 30 : 24

1) 4:1  2) 60/48

Step-by-step explanation:

1.  12: 3 is the same as 12/3 so you can diving both side by 3.

12:3 ÷ 3/3=4/1

2. 30:24 is the same as 30/24 so you can divide both sides by 6 or multiply both sides by 2.

30/24 * 2/2= 60/48

The volume of the box = 4 x the volume of cubical blocks;

The volume of cubical box = 2^3 = 8 cm3;

The volume of the box = 4 x 8 = 32 cm3;

The correct answer is B 32 cm3;
