A child playing with building blocks, which are of the shape of cubes, has built a structure. If the edge of each cube is 3 cm, find the volume of the structure built by the child.

Solution

$Volume of each cube = edge \times edge \times edge = 3 \times 3 \times 3 {cm}^{3}$
$= 27 {cm}^{3}$
$Number of cubes in the structure = 15$
$Therefore, volume of the structure = 27 \times 15 {cm}^{3} = 405 {cm}^{3}$

Volume of each cube = edge× edge× edge =3×3×3 cm3 =27 cm3 Number of cubes in the structure =15 Therefore, volume of the structure =27×15 cm3=405 cm3

$Volume of each cube = edge \times edge \times edge = 3 \times 3 \times 3 {cm}^{3}$
$= 27 {cm}^{3}$
$Number of cubes in the structure = 15$
$Therefore, volume of the structure = 27 \times 15 {cm}^{3} = 405 {cm}^{3}$
