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

Explanation

Number of cubes in the given structure = `1+2+3+4+5`=`15`

Edge of one cube = 3cm

Volume of cube=`(Edge)^3`

Volume of cube=`(3)^3`=`27 cm^3`

`therefore` Volume of the structure= `27xx15 cm^3`=`405 cm^3`
