Question

pls answer with process.....the 4th one

Answer 1

side of cube =5cm
volume of cube =5*5*5
                         =125cm³
dimensions of cuboid=40*15*20
volume of cuboid=12000cm³
number of cubes that can fit into the cuboid=
volume of cuboid/volume of cube
12000/125=96
therefore 96 cubes can fit in to the cuboid

Answer 2

Volume of cuboid = 40×15×20
volume of cube = 5×5×5
= 125
No. of cubes = 40×15×20 / 5×5×5
= 96 cubes.
