Sum of the volume of the cube is equals to 9 cubic units.
" Volume is defined as the total space occupied by three dimensional object enclosed in it."
Formula used
Volume of a cube = [tex](length)^{3}[/tex]
According to the question,
Given,
Edge of cube1 = 1unit
Edge of cube2 = 2units
Substitute the value in the formula to get the volume of a cube,
Volume of cube1 = [tex](1)^{3}[/tex]
= 1 cubic unit
Volume of cube2 = [tex](2)^{3}[/tex]
= 8 cubic unit
Sum of the volume of the cubes = Volume of cube1 + Volume of cube2
= 1 + 8
= 9 cubic units
Hence, sum of the volume of the cube is equals to 9 cubic units.
