Question

A child playing with building blocks, which are of the shape of the cubes, has built a structure as shown in figure. If the edge of each cube is $3cm$, find the volume of the structure built by the child. (in ${cm}^3$)

Answer 1

Volume of each cube $=3^3{cm}^3=27{cm}^3$

Volume of the structure $=$ Number of cubes $\times$volume of one cube

$=15\times 27$ ${cm}^3=405{cm}^3$
