Question

How many 2-cm cubes can fit in a box measuring 9cm by 4cm by 2cm?

Answer 1

let n be the number of cubes that can be fit in the given box
let s be the side of each cube =2cm
length l=9cm
breadth b=4cm
height h=2cm
volume of the box = l x b x h cm^3
The volume of'n' numbers of the cobes must be equal to the volume of the box
volume of n cubes = volume of the box
n x (s) ^3 = 9 x 4 x 2
n x 8=72
n =9
therefore 9 cubes can fit the given box.

Answer 2

Answer:

Step-by-step explanation:

let n be the number of cubes that can be fit in the given box

let s be the side of each cube =2cm

length l=9cm

breadth b=4cm

height h=2cm

volume of the box = l x b x h cm^3

The volume of'n' numbers of the cobes must be equal to the volume of the box

volume of n cubes = volume of the box

n x (s) ^3 = 9 x 4 x 2

n x 8=72

n =9

therefore 9 cubes can fit the given box.
