Question

What is the minimum number of cubical boxes with which one can completely fill a store-room of dimensions 20 m * 16 m x 12 m?
0 60
O 27
O 20
Indeterminate​

Answer 1

Step-by-step explanation:

the number of box to be minimum

the size of the required cubical box will be maximum

it will be equal to the hcf of the given no

so factorising

20= 2×2×5

16 = 2×2×2×2

12= 2×23

thus hcf

= 4

so the size of cubical box is 4m

now

number of cubical box be n

then n.volume of one box = volume of room

n×4^3= 20×16×12

n = 20×16×12/64

n= 60

thus minimum 60 box are required

hope it helps
