Answer:
the number of cubes that can be made are 10.
Step-by-step explanation:
volume of cuboid= length × breath × height
l=28 , b=14 , h=70
now volume of cuboid= 28×14×70
= 27440cm³
volume of cube= a³ , where a is edge of the cube
given that a= 14cm, then a³= 14×14×14 = 2744cm³
now the number of cube cam be made
= (volume of cuboid)÷(volume of cube)
= 27440÷ 2744
= 10 .
