a. how many metal cubical blocks of side 30cm can be cast by melting a rectangular piece of metal 3m X 75cm X 60 cm??​

Answer 1

Answer:

No. of Boxes that can be made = 50

Step-by-step explanation:

l×b×h of rectangular piece of metal = 3m×75cm×60cm

(3m = 300cm)

l×b×h = 300cm×75cm×60cm

Now, Volume of rectangular piece :-

l×b×h = 300×75×60

=1350000 cm^3

Side of cubical box =30 cm

Volume of 1 such box = Side×Side×Side

= 27000 cm^3

No. of cubes that can be formed from the rectangular metal :-

Volume of rectangular metal

Volume of 1 cubical box

1350000 ÷ 27000

=1350000/27000

=50

No. of Boxes that can be made = 50
