Answer:
Step-by-step explanation:
sameer has 80 one-centimetre cubes
he wants to create a cube with them so
volume of cuboid will be same as or less than volume all these cubes
volume of cubes
80 cubes * 1cm³
80 cm³
(a)long=6 cm, wide=5 cm, high=4 cm
volume = l* b* h
120 cm³
(b)long=8 cm, wide=5 cm, high=2 cm
volume = l* b* h
80 cm³
this cube can be perfectly made
(c)long=10 cm, wide=4 cm, high=5 cm
volume = l* b* h
200 cm³
(d)long=6 cm, wide=7 cm, high=2 cm
volume = l* b* h
84 cm³
(e)long=7 cm, wide=5 cm, high=2 cm
volume = l* b* h
70 cm³
we can also consider this
(f)long=10 cm, wide=4 cm, high=2 cm
volume = l* b* h
80 cm³
this cube can be perfectly made
best answers are
(b)long=8 cm, wide=5 cm, high=2 cm
(f)long=10 cm, wide=4 cm, high=2 cm
we can also consider this
(e)long=7 cm, wide=5 cm, high=2 cm
