Answer 2

Given:

$\text{Side of the cube} =12 \text{ cm}$

Find the volume of 1 cube:

$\text{Volume of a cube } = \text{Length}^3$

$\text{Volume of a cube } = \text{12}^3$

$\text{Volume of a cube } =1728 \text{ cm}^3$

Find the volume of 3 cubes:

$\text{Volume of 1 cube } = 1728 \text{ cm}^3$

$\text{Volume of 3 cubes } = 1728 \times 3$

$\text{Volume of 3 cubes } = 5184 \text{ cm}^3$

Find the height of the cuboid:

$\text{Volume of the cuboid} = 5184 \text { cm}^3$

$\text{Base Area of the cuboid} = 144 \text { cm}^2$

$\text{Height of the cuboid} =5184 \div 144$

$\text{Height of the cuboid} = 36 \text{ cm}$

Answer: The height is 36 cm
