Answer 1

${ \bf{ \underbrace{Appropriate \: Question:}}}$

A child playing with building blocks, which are of the shape of cubes, has built a structure as shown in fig.13.25. If the edge of each cube is 3 cm, find the volume of the structure built by the children.

${ \bf{ \underbrace{Required \: Solution :}}}$

◆ We know that,

↦ Volume of each cube = edge × edge × edge

Now, substitute the values :-

↦ 3 × 3 × 3 cm³ = 27 cm³

↦ Number of cubes in the structure = 15

↦ Therefore, Volume of structure = 27 × 15 cm³

↦ 405 cm³

■ Hence, the volume of the structure built by the children is 405 cm³.
