almost how many cubes of length 5 cm can be contained in a cuboid of length 20cm, breadth 10 cm, and height 5 cm?find it.​

volume of a cube=5³cm³

=125 cm³

volume of the cuboid=20×10×5

=1000 cm³

number of cubes=1000/125

=8 cubes

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
