Step-by-step explanation:
volume of cube = (edge)³
= 10³ = 1000 mm³
edge is halved = 10/2 = 5 mm
New Volume = 5³ = 125
Relation between volumes
1000:125
8:1

volume of cube:a^3
10^3
1000mm^3
1000^3 mm^3=1cm^3
edge when halved =10/2mm
=5mm
volume of new cube=a^3
5^3
125mm^3=0.125cm^3
now the relationship between both cubes is that the new cube is obtained from old cube and is 1/8 of old cube.
10^3
1000mm^3
1000^3 mm^3=1cm^3
edge when halved =10/2mm
=5mm
volume of new cube=a^3
5^3
125mm^3=0.125cm^3
now the relationship between both cubes is that the new cube is obtained from old cube and is 1/8 of old cube.
1000 mmcube = 1cm cube not 10cm cube , please correct , Similarly for 125mm cube = 0.125 cm cube
u r welcome
