Question

how many cubes of edge 4 cm can be cut from a cuboid whose length,breadth and height are 20 cm,18cm and 16cm respectively?

Answer 1

Answer:

Step-by-step explanation:

vol of cuboid = 36 x 16 x 10  

vol of cube = 16 x 4

no of cubes = vol of cuboid / vol of cube = 90

Answer 2

volume of cuboid = 20×18×16
= 360×16
= 5760cubic cm
and volume of single cube of edge 4 = 4×4×4=64
since no cubes =
$\frac{5760}{64} = \: 90$
90 cubes can be cut out
