Question

A solid cuboidal piece of iron measures 8cm × 2cm× 4cm. find its weight if 1 cu. cm. of iron weight 12 grams

Answer 1

volume of cuboid= l×b×h
=2×4×8
=62cm³
1cm³=12 gram
62cm³=62×12=744gram

Answer 2

hey mate !!

here is your answer !!


Answer

744 gram


in the questions GIVEN ,


length of the cuboidal piece of iron equal to 8cm


breadth of the cuboidal piece of iron equal to 2cm.

height of the cuboidal piece of iron equal to 4 cm.


here we find the volume of cuboid = l × b×h


using formula ,

v of cuboid = l × b × h

8 × 2 × 4

16 × 4

64 cm 3.

again ,

1 cm3 iron weight equal to 12 grams .

then ,

64 cm3 iron weight equal to 64 × 12 gm equal to 768 gram.


therefore total weight A solid cuboidal piece of iron equal to 768gram.
