the complete question in the attached figure
we know that
[volume of the box]=L*W*H
volume=24 cm³
case A) 10 cm long 4 cm wide and 10 cm hight
volume=10*4*10-----> volume=400 cm³
400 cm³ is not 24 cm³
case B) 2 cm long 2 cm wide and 6 cm high
volume=2*2*6-----> volume=24 cm³
24 cm³ is equal to 24 cm³----> could be the dimensions of the box
case C) 8 cm long 3 cm wide and 1 cm high
volume=8*3*1-----> volume=24 cm³
24 cm³ is equal to 24 cm³------> could be the dimensions of the box
the answer is
case B) 2 cm long 2 cm wide and 6 cm high
case C) 8 cm long 3 cm wide and 1 cm high
