Question

The internal dimensions of a closed box, made up of iron 1 cm thick, are 24 cm by to cha
12 cm. Find the volume of iron in the box.
​

Answer 1

Answer:

2096 c m 3

Step-by-step explanation:

Internal volume of the box =  l × b×h     = 24× 18× 12 = 5184 c m 3 .

External length =  [ 24+ ( 1 + 1 ) ] = 26   c m

External breadth =  [ 18 + ( 1 + 1 ) ] = 20 c m

External height =  [ 12 + (1 + 1 ) ] = 14  c m

External volume =  26 × 20 × 14 = 7280  c m 3

Volume of Iron =  7280 −  5184  = 2096   c m 3

Answer 2

Answer:

2096 cm^3

Step-by-step explanation

Internal volume of the box = l×b×h

=24×18×12=5184 cm

3

.

External length = [24+(1+1)]=26 cm

External breadth = [18+(1+1)]=20 cm

External height = [12+(1+1)]=14 cm

External volume = 26×20×14=7280 cm

3

Volume of Iron = 7280−5184=2096 cm
